ACT365 Rev 2, 10-Jan-13 FUNCTIONAL DESCRIPTION increases to ramp up the switch current to bring the secondary output back to regulation. The output regulation voltage is determined by the following relationship: As shown in the Functional Block Diagram, to regulate the output voltage in CV (constant voltage) mode, the ACT365 compares the feedback voltage at FB pin to the internal reference and generates an error signal to the pre-amplifier. The error signal, after filtering out the switching transients and compensated with the internal compensation network, modulates the external NPN transistor peak current at CS pin with current mode PFWM (Pulse Frequency and Width Modulation) control. To regulate the output current in CC (constant current) mode, the oscillator frequency is modulated by the output voltage. ⎛ R VOUTCV = 2.20V × ⎜⎜1 + FB1 R FB 2 ⎝ (1) where RFB1 (R5) and RFB2 (R6) are top and bottom feedback resistor, NS and NA are numbers of transformer secondary and auxiliary turns, and VD is the rectifier diode forward drop voltage at approximately 0.1A bias. SW is a driver output that drives the emitter of an external high voltage NPN transistor. This baseemitter-drive method makes the drive circuit the most efficient. Standby (No Load) Mode In no load standby mode, the ACT365 oscillator frequency is further reduced to a minimum frequency while the current pulse is reduced to a minimum level to minimize standby power. The actual minimum switching frequency is programmable with an output preload resistor. Fast Startup VDD is the power supply terminal for the ACT365. During startup, the ACT365 typically draws only 20μA supply current. The startup resistor from the rectified high voltage DC rail supplies current to the base of the NPN transistor. This results in an amplified emitter current to VDD through the SW pin via Active-Semi's proprietary fast-startup circuitry until it exceeds the VDDON threshold 19V. At this point, the ACT365 enters internal startup mode with the peak current limit ramping up in 10ms. After switching starts, the output voltage begins to rise. The VDD bypass capacitor must supply the ACT365 internal circuitry and the NPN base drive until the output voltage is high enough to sustain VDD through the auxiliary winding. The VDDOFF threshold is 5.5V; therefore, the voltage on the VDD capacitor must remain above 5.5V while the output is charging up. Loop Compensation The ACT365 integrates loop compensation circuitry for simplified application design, optimized transient response, and minimal external components. Output Cable Resistance Compensation The ACT365 provides programmable output cable resistance compensation during constant voltage regulation, monotonically adding an output voltage correction up to predetermined percentage at full power. There are four levels to program the output cable compensation by connecting a resistor (R10 in Figure 3) from the SW pin to VDD pin. The percentage at full power is programmable to be 3%, 6%, 9% or 12%, and by using a resistor value of 300k, 150k, 75k or 33k respectively. If there is no resistor connection, there is no cord compensation. Constant Voltage (CV) Mode Operation This feature allows for better output voltage accuracy by compensating for the output voltage droop due to the output cable resistance. In constant voltage operation, the ACT365 captures the auxiliary flyback signal at FB pin through a resistor divider network R5 and R6 in Figure 6. The signal at FB pin is pre-amplified against the internal reference voltage, and the secondary side output voltage is extracted based on Active-Semi's proprietary filter architecture. Constant Current (CC) Mode Operation When the secondary output current reaches a level set by the internal current limiting circuit, the ACT365 enters current limit condition and causes the secondary output voltage to drop. As the output voltage decreases, so does the flyback voltage in a proportional manner. An internal current shaping circuitry adjusts the switching frequency based on the flyback voltage so that the transferred power remains proportional to the output voltage, resulting This error signal is then amplified by the internal error amplifier. When the secondary output voltage is above regulation, the error amplifier output voltage decreases to reduce the switch current. When the secondary output voltage is below regulation, the error amplifier output voltage Innovative PowerTM ⎞ NS ⎟⎟ × − VD ⎠ NA -5- www.active-semi.com Copyright © 2013 Active-Semi, Inc.

The energy transferred to the output during each switching cycle is ½(LP × ILIM2) × η, where LP is the transformer primary inductance, ILIM is the primary peak current, and η is the conversion efficiency. From this formula, the constant output current can be derived: IOUTCC = ⎛ 0 . 396 V × 0 . 9 1 × LP × ⎜⎜ 2 R CS ⎝ 2 ⎞ ⎛ η × fSW ⎟⎟ × ⎜⎜ ⎠ ⎝ VOUTCV ⎞ ⎟⎟ ⎠ die temperature. The typical over temperature threshold is 135°C with 20°C hysteresis. When the die temperature rises above this threshold the ACT365 is disabled until the die temperature falls by 20°C, at which point the ACT365 is re-enabled. TYPICAL APPLICATION Design Example (2) The design example below gives the procedure for a DCM flyback converter using the ACT365. Refer to Application Circuit in Figure 3, the design for a adapter application starts with the following specification: where fSW is the switching frequency and VOUTCV is the nominal secondary output voltage. The constant current operation typically extends down to lower than 40% of nominal output voltage regulation. Input Voltage Range Primary Inductance Compensation The ACT365 integrates a built-in proprietary (patent-pending) primary inductance compensation circuit to maintain constant current regulation despite variations in transformer manufacturing. The compensated range is ±7%.

This voltage supplies the primary winding of the transformer T1 and the startup resistor R7. The primary power current path is formed by the transformer’s primary winding, the NPN transistor, the ACT365 internal MOSFET and the current sense resistor R9. The network consisting of capacitor C4 and diode D6 provides a VDD supply voltage for ACT365 from the auxiliary winding of the transformer. C4 is the decoupling capacitor of the supply voltage and energy storage component for startup. The diode D8 and the capacitor C5/C6 rectifies and filters the output voltage. The resistor divider consisting of R5 and R6 programs the output voltage. The ACT365 integrates a primary inductor peak current limit compensation circuit to achieve constant input power over line and load ranges. Protection The ACT365 incorporates multiple protection functions including over-voltage, over-current and over-temperature. Output Short Circuit Protection When the secondary side output is short circuited, the ACT365 enters hiccup mode operation. In this condition, the VDD voltage drops below the VDDOFF threshold and the auxiliary supply voltage collapses. This turns off the ACT365 and causes it to restart. This hiccup behavior continues until the short circuit is removed. The minimum and maximum DC input voltages can be calculated: Output Over Voltage Protection The ACT365 includes output over-voltage protection circuitry, which shuts down the IC when the output voltage is 40% above the normal regulation voltage for 4 consecutive switching cycles. The ACT365 enters hiccup mode when an output over voltage fault is detected.

PCB Layout Guideline (9) Good PCB layout is critical to have optimal performance. Decoupling capacitor (C4), current sense resistor (R9) and feedback resistor (R5/R6) should be placed close to VDD, CS and FB pins respectively. There are two main power path loops. One is formed by C1/C2, primary winding, NPN transistor and the ACT365. The other is the secondary winding, rectifier D8 and output capacitors (C5,C6). Keep these loop areas as small as possible.

I PK = 1 . 0 mH = 110 80 nH / T 2 The number of turns of secondary and auxiliary windings can be derived when Np/Ns=14: When the transistor is turned off, the voltage on the transistor’s collector consists of the input voltage and the reflected voltage from the transformer’s secondary winding. There is a ringing on the rising top edge of the flyback voltage due to the leakage inductance of the transformer. This ringing is clamped by a RCD network if it is used. Design this clamped voltage as 50V below the breakdown of the NPN transistor. The flyback voltage has to be considered with selection of the maximum reverse voltage rating of secondary rectifier diode.

VFB Sampling Waveforms ACT365 senses the output voltage information through the VFB waveforms. Proper VFB waveforms are required for IC to operate in a stable status. To avoid mis-sampling, 1.0µs blanking time is added to blank the ringing period due to the leakage inductance and the circuit parasitic capacitance. Figure 2 is the recommended VFB waveform to guarantee the correct sampling point so that the output information can be sent back into the IC to do the appropriate control.
