Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | INV | input | Inverting input of the error amplifier, fed from the output voltage divider, normally high impedance and sinking a current from TBO only when tracking boost is used. |
| 2 | COMP | output | Error amplifier output with a compensation network to INV, and the gate driver is inhibited (burst-mode operation) when the voltage falls below 2.4 V. |
| 3 | MULT | input | Mains input to the multiplier, connected to the rectified mains through a resistor divider, providing the sinusoidal current-loop reference and the RMS mains information. |
| 4 | CS | input | Input to the PWM comparator for MOSFET current sensing, where a second level at 1.7 V detects abnormal currents and temporarily stops the converter. |
| 5 | VFF | input | Second multiplier input for the 1/V² function, requiring a capacitor and parallel resistor to GND, and it must never be connected directly to GND but through a resistor between 100 kΩ (min) and 2 MΩ (max). |
| 6 | TBO | passive | Tracking boost pin providing a buffered VFF voltage, where a resistor to GND sets the current sunk from INV, and it must be left open if the function is not used. |
| 7 | PFC_OK | input | PFC output voltage monitor and remote disable, where the IC stops switching above 2.5 V, shuts down below 0.23 V (restarts above 0.27 V), and latches off on feedback failure when INV is below 1.66 V. |
| 8 | PWM_LATCH | output | Fault output asserted high on feedback failure to latch off the cascaded dc-dc PWM controller, high impedance in normal operation and left floating if not used. |
| 9 | PWM_STOP | output | Fault output pulled to ground when RUN is below 0.8 V to temporarily stop the dc-dc PWM controller, high impedance in normal operation with a maximum sink current of 3 mA. |
| 10 | RUN | input | Remote ON/OFF control where a voltage below 0.8 V shuts down the IC without latching and restart occurs above 0.88 V, and it can be connected to VFF for brownout protection. |
| 11 | ZCD | input | Boost inductor demagnetization sensing input for transition-mode operation, where a negative-going edge triggers MOSFET turn-on, with a maximum current of -10 mA (source) and 10 mA (sink). |
| 12 | GND | power_in | Ground, serving as the current return for both the signal part of the IC and the gate driver. |
| 13 | GD | output | Totem-pole gate driver output for power MOSFETs and IGBTs with 600 mA peak source and 800 mA peak sink current, with the high level clamped at about 12 V. |
| 14 | Vcc | power_in | Supply voltage for both the signal part of the IC and the gate driver, self-limited at 20 mA, with a bypass capacitor of about 0.1 µF typical to GND suggested for a clean bias. |
