Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | INV | input | Inverting input of error amplifier for output voltage feedback via resistor divider; input impedance high, can sink current from TBO pin during tracking boost operation. |
| 2 | COMP | output | Error amplifier output with frequency compensation network to INV pin; output clamp voltage 2.1 to 6.7V depending on input state. |
| 3 | MULT | input | Multiplier main input receiving rectified mains voltage reference via resistor divider; linear operation 0 to 3V with internal clamp at 9 to 9.5V. |
| 4 | CS | input | PWM comparator current sense input detecting MOSFET current through sense resistor; normal operation limit ~1.08V for turn-off comparison. |
| 5 | VFF | input | Voltage feedforward input for 1/V² compensation; connect external RC peak-holding network to ground; operating range 0.5 to 3V with 20mV dropout from MULT peak. |
| 6 | TBO | output | Tracking boost output providing buffered VFF voltage; external resistor to ground defines mains-tracking current sink from INV pin (maximum current 0.25mA). |
| 7 | PFC_OK | input | PFC output voltage monitor input for feedback failure protection; latch-off when exceeds 2.5V or auto-disable when below 0.2V with re-enable threshold 0.26V. |
| 8 | PWM_LATCH | tri_state | Open-source fault output asserted high (3.7V minimum) when PFC_OK exceeds 2.5V for feedback failure detection; signals cascaded DC-DC converter PWM controller with latched shutdown. |
| 9 | PWM_STOP | tri_state | Open-drain fault output pulled low (1V at 0.5mA sink) when RUN input disabled below 0.52V; signals temporary disable to cascaded DC-DC converter PWM controller. |
| 10 | RUN | input | Remote ON/OFF control input for brownout protection; disable threshold 0.5 to 0.54V, re-enable threshold 0.56 to 0.64V with hysteresis for non-latched shutdown. |
| 11 | ZCD | input | Zero-current detector input for boost inductor demagnetization sensing in transition-mode operation; negative-going edge triggers MOSFET turn-on. |
| 12 | GND | power_in | Ground; signal and power current return for IC logic and gate driver output stage. |
| 13 | GD | output | Gate driver output with 600mA source and 800mA sink peak current capability for driving power MOSFETs and IGBTs; output voltage clamped to approximately 12V. |
| 14 | VCC | power_in | Supply voltage for IC logic and gate driver stages; operating range 10.3 to 22V with turn-on at 11 to 13V, turn-off at 8.7 to 10.3V, and Zener clamp at 22 to 25V. |
