Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | EN/UV | input | Enable / Line Under-Voltage sense input. Dual-function pin: a low-impedance source-follower (~1.2 V) whose current is compared to a ~115 uA threshold to enable/disable MOSFET switching (typically driven by an optocoupler), and a line under-voltage sense input that measures current (~25 uA start / ~1 uA disable) from an external resistor to the DC bulk to inhibit switching under low-line conditions. |+| 2 | BP/M | power_in | Bypass / Multi-Function pin. Connection for the external bypass capacitor of the internally generated 5.85 V supply; capacitor value (0.1 uF / 1 uF / 10 uF) also selects the current-limit mode. A 6.4 V shunt clamp allows external biasing via a bias winding, and shutdown latches when the current into this pin exceeds 5.5 mA (releases when BP/M drops below 4.9 V). |+| 4 | D | power_in | DRAIN pin - connection to the drain of the internal 700 V power MOSFET. Also provides the internal operating current for start-up and steady-state operation via the high-voltage switched current source. |+| 5 | S | power_in | SOURCE pin - internally connected to the power MOSFET source. Serves as the high-voltage power return and control-circuit common. Multiple source pins (5-8) are tied internally and used to improve heatsinking to the PCB while providing extended creepage from the DRAIN pin. |+| 6 | S | power_in | SOURCE pin - internally connected to the power MOSFET source. Serves as the high-voltage power return and control-circuit common. Multiple source pins (5-8) are tied internally and used to improve heatsinking to the PCB. |+| 7 | S | power_in | SOURCE pin - internally connected to the power MOSFET source. Serves as the high-voltage power return and control-circuit common. Multiple source pins (5-8) are tied internally and used to improve heatsinking to the PCB. |+| 8 | S | power_in | SOURCE pin - internally connected to the power MOSFET source. Serves as the high-voltage power return and control-circuit common.
