To provide low power consumption at light loads, this device reduces the switching frequency in small steps with load, towards an adjustable minimum (e. g. 20 kHz in standby mode). Additionally, the startup current is very low. To avoid switching stress on the power devices, the power transistor is always switched on at minimum voltage. A special circuit is implemented to avoid jitter. The device has Version 2.0 3 31 Jul 2003 TDA 16846/16846-2 TDA 16847/16847-2 several protection functions: VCC over- and undervoltage, mains undervoltage, current limiting and 2 free usable fault comparators. Regulation can be done by using the internal error amplifier or an opto coupler feedback (additional input). The output driver is ideally suited for driving a power MOSFET. Fixed frequency and synchronized operation are also possible. The TDA 16846-2 is suited for TV-, VCR- sets, SAT receivers and other sets for consumer electronics. It also can be used in PC monitors. The TDA 16847-2 is identical with TDA 16846-2 but has an additional power measurement output (pin 8) which can be used as a Temporary High Power Circuit.

The output of a voltage divider between the control winding and ground is connected to this input. If the pulses at pin 3 exceed a 5 V threshold, the control voltage at pin 4 is lowered. 4 This is the pin for the control voltage. A capacitor has to be connected between this pin and ground. The value of this capacitor determines the duration of the softstart and the speed of the control (primary regulation). 5 If an opto coupler for the control is used, its output has to be connected between this pin and ground. The voltage divider at pin 3 has then to be changed, so that the pulses at pin 3 are below 5 V. 6 Fault comparator 2: A voltage > 1.2 V at this pin stops the SMPS (v.also pin 9). 7 If fixed frequency mode is wanted, a parallel RC circuit has to be connected between this pin and ground. The RC-value determines the frequency. If synchronized mode is wanted, sync pulses have to be fed into this pin. 8 TDA 16846-2: Not connected. TDA 16847-2: This is the power measurement output of the Temporary High Power Circuit. A capacitor and a RC-circuit has to be connected between this pin and ground. 9 Output for the reference voltage (5 V). With a resistor between this pin and ground the fault comparator 2 (pin 6) is enabled. 10 Fault comparator 1: If a voltage > 1 V is applied to this pin, the SMPS stops. 11 This is the input of the primary voltage check. The voltage at the anode of the primary electrolytic capacitor has to be fed to this pin via a voltage divider. If the voltage of this pin falls below 1 V, the SMPS is switched off. A second function of this pin is the primary voltage dependent fold back point correction (only active in free running mode). 12 Common ground. 13 Output signal. This pin has to be connected via a series resistor to the gate of the power transistor. 14 Connection for supply voltage and startup capacitor. After startup, the supply voltage is produced by the control winding of the transformer and rectified by an external diode. Version 2.0 5 31 Jul 2003 TDA 16846/16846-2 TDA 16847/16847-2 1.5 Figure 2 Version 2.0 Block Diagrams TDA 16846-2 6 31 Jul 2003 TDA 16846/16846-2 TDA 16847/16847-2 Figure 3 Version 2.0 TDA 16847-2 7 31 Jul 2003 TDA 16846/16846-2 TDA 16847/16847-2 2 Functional Description Start Up Behaviour (Pin 14) When power is applied to the chip and the voltage V14 at Pin 14 (VCC) is less than the upper threshold (VON) of the Supply Voltage Comparator (SVC), then the input current I14 will be less than 100 µA. The chip is not active (off state) and driver output (Pin 13) and control output (Pin 4) will be actively held low. When V14 exceeds the upper SVC threshold (VON) the chip starts working and I14 increases. When V14 falls below the lower SVC threshold (VOFF) the chip starts again from its initial condition. Figure 4 shows the start-up circuit and Figure 5 shows the voltage V14 during start up. Charging of C14 is done by resistor R2 of the “Primary Current Simulation” (see later) and the internal diode D1, so no additional start up resistor is needed. The capacitor C14 delivers the supply current until the auxiliary winding of the transformer supplies the chip with current through the external diode D14. It is recommended to apply a small RF snubber capacitor of e.g. 100 nF parallel to the electrolytic capacitor at pin 14 as shown in the application circuits in Figures 15, 16 , and 17. To avoid multiple pulses during start up in fixed frequency mode (danger of transformer saturation), the IC works in freerunning mode until the pulses at pin 3 (RZI) exceed the 2.5 V threshold (only TDA 16846-2, TDA 16847-2). Figure 4 Version 2.0 Startup Circuit 8 31 Jul 2003 TDA 16846/16846-2 TDA 16847/16847-2 Figure 5 Startup Voltage Diagram Primary Current Simulation PCS (Pin 2) / Current Limiting A voltage proportional to the current of the power transistor is generated at Pin 2 by the RC-combination R2, C2 (Figure 4). The voltage at Pin 2 is forced to 1.5 V when the power transistor is switched off and during its switch on time C2 is charged by R2 from the rectified mains. The equation of V2 and the current in the power transistor (Iprimary) is : V 2 = 1,5 V + L primary × I primary -------------------------------R2 × C2 Lprimary: Primary inductance of the transformer The voltage V2 is applied to one input of the On Time Comparator ONTC (see Figure 2). The other input is the control voltage. If V2 exceeds the control voltage, the driver switches off (current limiting). The maximum value of the control voltage is the internal reference voltage 5 V, so the maximum current in the power transistor (IMprimary) is : 3,5 V × R 2 × C 2 I Mprimary = -------------------------------------L primary The control voltage can be reduced by either the Error Amplifier EA (current mode regulation), or by an opto coupler at Pin 5 (regulation with opto coupler isolation) or by the voltage V11 at Pin 11 (Fold Back Point Correction). Version 2.0 9 31 Jul 2003 TDA 16846/16846-2 TDA 16847/16847-2 Fold Back Point Correction PVC (Pin 11) V11 is derived from a voltage divider connected to the rectified mains and reduces the limit of the possible current maximum in the power transistor if the mains voltage increases. I.e. this limit is independent of the mains (only active in free running mode). The maximum current (IMprimary) depending on the voltage V11 at Pin 11 is : (4 V – V 11 ⁄ 3 ) × R 2 × C 2 I Mprimary = ----------------------------------------------------------L primary Off-Time Circuit OTC (Pin 1) Figure 6 shows the Off-Time Circuit which determines the load dependent frequency curve. When the driver switches off (Figure 7) the capacitor C1 is charged first by current I1L (approx. 0.5 mA, for extended ringing suppression time). As soon as the voltage at pin 3 reaches the level V3L (2.5 V), the charging current is switched to the higher value I1H (approx. 1 mA, for normal ringing suppression time). This current flows until the capacitor’s voltage reaches 3.5 V. The charge time TC1 is : C 1 × 1,5 V TC1 ≈ ------------------------1mA For proper operation of the special internal anti- jitter circuit, TC1 (rising time for I1H only) should have the same value as the resonance time “tR” of the power circuit (Figure 7). After charging C1 up to 3.5 V the current source is disconnected and C1 is discharged by resistor R1. The voltage V1 at Pin 1 is applied to the Off-Time Comparator (OFTC). The other input of OFTC is the control voltage. The value of the control voltage at the input of OFTC is limited to a minimum of 2 V (for stable frequency at very light load). The OnTime Flip Flop (ONTF) is set, if the output of OFTC is high 1) and the voltage V3 at Pin 3 falls below 25 mV (zero crossing signal is high). This ensures switching on of the power transistor at minimum voltage. If no zero crossing signal is coming into pin 3, the power transistor is switched on after an additional delay until V1 falls below 1.5 V (see Figure 6, OFTCD). As long as V1 is higher than the limited control voltage, ONTF is disabled to suppress wrong zero crossings of V3, due to parasitic oscillations from the transformer after switch-off. The discharge time of C1 is a function of the control voltage. 1) i.e. V1 is less than the limited control voltage. . Control Voltage Output Power Off-time TD1 1.5 - 2 V Low Constant (TD1MAX.), const. frequency stand by 2 - 3.5 V Medium Decreasing 3.5 - 5 V High Free running, switch-on at first minimum Version 2.0 10 31 Jul 2003 TDA 16846/16846-2 TDA 16847/16847-2 If the control voltage is below 2 V (at low output power) the “off-time” is maximum and constant TD1 max ≈ 0, 56 × R 1 × C 1 During the discharge time tD1, V1 must not fall below the limit V1L, otherwise the function is not guaranteed.

Figure 8 Version 2.0 Load Dependent Frequency Curve 12 31 Jul 2003 TDA 16846/16846-2 TDA 16847/16847-2 Error Amplifier EA / Soft-Start (Pin 3, Pin 4) Figure 9 shows the simplified Error Amplifier circuit. The positive input of the Error Amplifier (EA) is the reference voltage 5 V. The negative input is the pulsed output voltage from the auxiliary winding, divided by R31 and R32. The capacitor C3 is dimensioned only for delaying zero crossings and smoothing the first spike after switchoff. Smoothing of the regulation voltage is done with the soft start capacitor C4 at Pin 4. During start up C4 is charged with a current of approx. 2 µA (Soft Start). For primary regulation C4 is charged and discharged with pulsed currents. Figure 10 shows the voltage diagrams of the Error Amplifier circuit. Figure 9 Error Amplifier Figure 10 Regulation Pulse Diagram Version 2.0 13 31 Jul 2003 TDA 16846/16846-2 TDA 16847/16847-2 Fixed Frequency and Synchronization Circuit SYN (Pin 7) Figure 11 shows the Fixed Frequency and Synchronization Circuit. The circuit is disabled when Pin 7 is not connected or connected to pin 9 (Vref, to avoid noise sensitivity). With R7 and C7 at Pin 7 the circuit is working. C7 is charged fast with approx. 1 mA and discharged slowly by R7 (Figure 11). The power transistor is switched on at beginning of the charge phase. The switching frequency is (charge time ignored) : 0, 8 f ≈ -------------R7 × C7 When the oscillator circuit is working the Fold Back Point Correction is disabled (not necessary in fixed frequency mode). “Switch on” is only possible when a “zero crossing” has occurred at Pin 3, otherwise “switch-on” will be delayed (Figure 12).

The synchronization frequency must be higher than the oscillator frequency. Figure 13 Version 2.0 Ext. Synchronization Circuit 15 31 Jul 2003 TDA 16846/16846-2 TDA 16847/16847-2 3 Protection Functions The chip has several protection functions: Current Limiting See “Primary Current Simulation PCS (Pin 2) / Current Limiting” and “Fold Back Point Correction PVC (Pin 11)”. Over- and Undervoltage Lockout OV/SVC (Pin 14) When V14 at Pin 14 exceeds 16.5 V, e. g. due to a fault in the regulation circuit, the Error Flip Flop ERR is set and the output driver is shut-down. When V14 goes below the lower SVC threshold, ERR is reset and the driver output (Pin 13) and the soft-start (Pin 4) are shut down and actively held low. Primary Voltage Check PVC (Pin 11) When the voltage V11 at Pin 11 goes below 1 V the Error Flip Flop (ERR) is set. E.g. a voltage divider from the rectified mains at Pin 11 prevents high input currents at a too low input voltage. Free Usable Fault Comparator FC1 (Pin 10) When the voltage at Pin 10 exceeds 1 V, the Error Flip Flop (ERR) is set. This can be used e. g. for mains overvoltage shutdown. Free Usable Fault Comparator FC2 (Pin 6) When the voltage at Pin 6 exceeds 1.2 V, the Error Flip Flop (ERR) is set. A resistor between Pin 9 (REF) and ground is necessary to enable this fault comparator. Voltage dependent Ringing Suppression Time During start-up and short-circuit operation, the output voltage of the converter is low and parasitic zero crossings are applied for a longer time at Pin 3. Therefore the Ringing Suppression Time TC1 (see “Off-Time Circuit OTC (Pin 1)”) is extended with a factor of 2.2 at a low output voltage. The voltage at pin 1 must not fall below the limit V1L. Version 2.0 16 31 Jul 2003 TDA 16846/16846-2 TDA 16847/16847-2 4 Temporary High Power Circuit FC2, PMO, REF (Pin 6, 8, 9, TDA 16847-2) Figure 14 shows the Temporary High Power Circuit: Figure 14 The Temporary High Power Circuit (THPC) consists of two parts: Firstly, a power measurement circuit is implemented: The capacitor C8 at Pin 8 is charged with a constant current I8 during the discharge time of the flyback transformer and grounded the other time. Thus the average of the sawtooth voltage V8 at Pin 8 is proportional to the converter´s output power (at constant output voltages). The charge current I8 for C8 is set by the resistor R9 at Pin 9: I8 = 5 V/R9 Version 2.0 17 31 Jul 2003 TDA 16846/16846-2 TDA 16847/16847-2 Secondly, a High Power Shutdown Comparator (FC2) is implemented: When the voltage V6 at Pin 6 exceeds 1.2 V the Error Flip Flop (ERR) is set. The output voltage of the power measurement circuit (Pin 8) is smoothed by R8/C6 and applied to the “high power shutdown” input at Pin 6. The relation between this voltage V6 and the output power of the converter P is approximately: V6 ≈ (P × LSecondary × 5 V)/(VOUT2 × C8 × R9) LSecondary: The transformers secondary inductance VOUT: The converters output voltage So the time constant of R9/C8 for a certain high power shutdown level PSD is: R9 × C8 ≈ (PSD × LSecondary × 4.2)/VOUT2 The converters high power shutdown level can be adjusted lower (by R9, C8) than the current limit level (see “current limiting”). Thus because of the delay R8/C6, the converter can deliver maximum output power (current limit level) for a certain time (e. g. for power pulses like motor start current) and a power below the high power shutdown level for an unlimited time. This is of advantage because the thermal dimensioning of the power devices needs to be done for the lower power level only. Once the voltage V6 exceeds 1.2 V no more charging or discharging happens at Pin 8. The voltage V6 remains high due to the bias current out of FC2 and the converter remains switched-off. Reset can be done either by plugging-off the supply from the mains or by a high value resistor R6 (Figure 14). R6 causes a reset every few seconds. When Pin 9 is not connected or gets too little current (I9 < I9FC2), the temporary high power circuit is disabled.
