TEA1530T/AT/AP GreenChip II SMPS control IC Rev. 01 — 30 June 2008 Product data sheet 1. General description The GreenChip II is the second generation of green Switched Mode Power Supply (SMPS) controller ICs. Its high level of integration allows the design of a cost effective power supply with a very low number of external components. The TEA1530(A) (TEA1530T, TEA1530AT and TEA1530AP) can be used in fixed frequency converter designs for low voltage, high current applications. At low power (standby) levels, the system operates in cycle skipping mode which minimizes the switching losses during standby. The proprietary high voltage BCD800 process makes direct start-up possible from the rectified universal mains voltage in an effective and green way. A second low voltage BICMOS IC is used for accurate, high speed protection functions and control. The TEA1530(A) enables highly efficient and reliable supplies to be designed easily. 2.

Functional description The TEA1530(A) is the controller of a compact flyback converter, with the IC situated at the primary side. An auxiliary winding of the transformer powers the IC after start-up; see Figure 3. TEA1530T_AT_AP_1 Product data sheet © NXP B.V. 2008. All rights reserved.

Rev. 01 — 30 June 2008 5 of 21 TEA1530T/AT/AP NXP Semiconductors GreenChip II SMPS control IC 7.1 Start-up, mains enabling operation level and undervoltage lockout Refer to Figure 8 and Figure 9. Initially, the IC is self supplying from the rectified mains voltage via pin DRAIN. The supply capacitor CVCC (at pin 1) is charged by the internal start-up current source to a level of about 4 V or higher, depending on the drain voltage. Once the drain voltage exceeds the Vmains(oper)(en) (mains-dependent operation-enabling level), the start-up current source will continue charging capacitor CVCC (switch S1 will be opened), see Figure 1. The IC activates the power converter as soon as the voltage on pin VCC passes the Vstartup level. At this moment the IC supply from the high voltage pin is stopped (green function). The IC supply is taken over by the auxiliary winding of the flyback converter. The moment the voltage on pin VCC drops below Vth(UVLO) (undervoltage lockout), the IC stops switching and performs a safe restart from the rectified mains voltage. In the safe restart mode the driver output is disabled and the voltage on pin VCC is recharged via the pin DRAIN. 7.2 Supply management All (internal) reference voltages are derived from a temperature compensated, on-chip band gap circuit. 7.3 Current control mode Current control mode is used for its good line regulation behavior. The primary current is sensed across an external resistor and compared with the internal control voltage. The driver output is latched in the logic, preventing multiple switch-on. The internal control voltage is inversely proportional to the voltage on the external pin CTRL with an offset of 1.5 V. This means that a voltage range from 1 V to approximately 1.5 V on pin CTRL will result in a pin SENSE voltage range from 0.52 V to 25 mV (a high external control voltage results in a low duty cycle). coa016 Vsense(max) (V) 0.52 V cycle skip active 25 mV 1V (typ) Fig 5. 1.5 V (typ) VCTRL (V) The Vsense(max) voltage as a function of VCTRL 7.4 Oscillator The fixed frequency of the oscillator is set by an internal current source and capacitor.

Rev. 01 — 30 June 2008 6 of 21 TEA1530T/AT/AP NXP Semiconductors GreenChip II SMPS control IC 7.5 Cycle skipping At very low power levels, a cycle skipping mode activates. An internal control voltage (Vsense(max)) lower than 25 mV will inhibit switch-on of the external power MOSFET until this voltage increases to a higher value; see Figure 5. 7.6 Continuous Conduction Mode (CCM) The IC operates in Fixed Frequency Continuous Conduction Mode (FF CCM). Pin DRAIN should be connected to the high voltage rectified mains VI; see Figure 8. 7.7 OverCurrent Protection (OCP) The primary peak current in the transformer is measured accurately cycle-by-cycle using the external sense resistor Rsense. The OCP circuit limits the voltage on pin SENSE to an internal level equal to 1.5 V − VCTRL (see also Section 7.3). The OCP detection is suppressed during the leading edge blanking period, tleb to prevent false triggering caused by the switch-on spikes. 7.8 Control pin protection If pin CTRL becomes open-circuit or is disconnected, a fault condition is assumed and the converter will stop switching immediately. Operation recommences when the fault condition is removed. 7.9 Adjustable slope compensation A slope compensation function has been added at pin CTRL; see Figure 6. The slope compensation function prevents subharmonic oscillation in CCM at duty cycles over 50 %. The CTRL voltage is modulated by sourcing a (non-constant) current out of pin CTRL and by adding externally a series resistor Rslopecomp. This increases the CTRL voltage proportionally with the on-time, which therefore limits the OCP level. A longer on-time results in a higher CTRL voltage, this increase in CTRL voltage will decrease the on-time. Slope compensation can be adjusted by changing the value of Rslopecomp. Slope compensation prevents modulation of the on-time (duty cycle) while operating in FF CCM. A possible drawback of subharmonic oscillation can be output voltage ripple.

Slope compensation 7.10 Minimum and maximum on-time The minimum on-time of the SMPS is determined by the LEB time (typically 400 ns). The IC limits the maximum on-time by limiting the driver duty cycle to 70 %. So the maximum on-time is correlated to the oscillator time which results in an accurate limit of the minimum input voltage of the flyback converter. 7.11 PROTECT and timing input The PROTECT input (pin 3) is a multipurpose, high-impedance input, which can be used to switch off the IC and create a relatively long timing function. As soon as the voltage on this pin rises above 2.5 V, switching stops immediately. For the timing function, a current of typically 50 µA flows out of pin PROTECT and charges an external capacitor until the activation level of 2.5 V is reached. This current source is only activated when the converter is not in regulation, which is detected by the voltage on pin CTRL (VCTRL < 0.63 V). A (small) discharge current is also implemented to ensure that the capacitor is not charged, for example, by spikes. An internal MOSFET switch is added to discharge the external capacitor and ensures a defined start situation. For the TEA1530AP and TEA1530AT the voltage on pin CTRL determines whether the IC enters latched protection mode or safe restart protection mode: • When the voltage on pin CTRL is below 0.63 V, the IC is assumed to be out of regulation (e.g. the control loop is open). In this case activating pin PROTECT (VPROTECT > 2.5 V) will cause the converter to stop switching. Once VCC drops below Vth(UVLO), capacitor CVCC will be recharged and the supply will restart. This cycle will be repeated until the fault condition is removed (safe restart mode). • When the voltage on pin CTRL is above 0.63 V, the output is assumed to be in regulation. In this case activating pin PROTECT (VPROTECT > 2.5 V), by external means, will activate the latch protection of the IC. The voltage on pin VCC will cycle between Vstartup and Vth(UVLO), but the IC will not start switching again until the latch TEA1530T_AT_AP_1 Product data sheet © NXP B.V. 2008. All rights reserved. Rev. 01 — 30 June 2008 8 of 21 TEA1530T/AT/AP NXP Semiconductors GreenChip II SMPS control IC protection is reset. The latch is reset as soon as VCC drops below 4.5 V (typical value) (this only occurs when the mains has been disconnected). The internal overtemperature protection will also trigger this latch; see also Figure 1. For the TEA1530T the IC always enters the latched mode protection independent of the voltage on pin CTRL. A voltage higher than 3 V on pin PROTECT will always latch the IC. This is independent of the state of the IC. 7.12 OverTemperature Protection (OTP) The IC provides accurate OTP. The IC stops switching when the junction temperature exceeds the thermal shutdown temperature. When VCC drops to Vth(UVLO), capacitor CVCC is recharged to the Vstartup level, however, switching will not restart. Subsequently, VCC will drop again to Vth(UVLO). Operation only recommences when VCC drops below a level of about 4.5 V, typically when the mains voltage is disconnected for a short period. 7.13 Soft start-up (pin SENSE) To prevent transformer rattle at start-up or during hiccup, the transformer peak current is slowly increased by the soft start function. This can be achieved by inserting a resistor and a capacitor between pin SENSE (pin 5) and sense resistor Rsense. An internal current source charges the capacitor to VSENSE = Istartup(soft) × Rss (about 0.5 V maximum). The start level and the time constant of the increasing primary current level can be adjusted externally by changing the values of Rss and Css. V sense ( max ) – ( I startup(soft) × R ss ) I DM = -------------------------------------------------------------------------------R sense τ = R ss × C ss The charging current Istartup(soft) will flow as long as the voltage on pin SENSE is below approximately 0.5 V. If the voltage on pin SENSE exceeds 0.5 V, the soft start current source will start limiting current Istartup(soft). At Vstartup, the Istartup(soft) current source is completely switched off, see Figure 7. Since the soft start current Istartup(soft) is supplied from pin DRAIN, the Rss value will not affect VCC current during start-up. TEA1530T_AT_AP_1 Product data sheet © NXP B.V. 2008.

Soft start-up 7.14 Driver The driver circuit to the gate of the power MOSFET has a current sourcing capability of typically 150 mA and a current sink capability of typically, 500 mA at VCC = 9.5 V. At VCC = 15 V, the current sourcing capability is typically 250 mA and the current sink capability typically 0.7 A. This permits fast turning on and off of the power MOSFET for efficient operation. A low driver source current has been chosen to limit the ∆V/∆t at switch-on. This reduces ElectroMagnetic Interference (EMI) and also limits the current spikes across Rsense. 8.

Application information A converter with the TEA1530(A) consists of an input filter, a transformer with a third winding (auxiliary), and an output stage with a feedback circuit. Capacitor CVCC buffers the IC supply voltage, which is powered via the internal current source, that is connected to the rectified mains, during start-up and via the auxiliary winding during operation. A sense resistor Rsense converts the primary current into a voltage at pin SENSE. The value of Rsense defines the maximum primary peak current. Figure 8 shows a typical CCM flyback configuration.
