PN8034SSC-R1B

Wuxi Chipown Micro electronics · AC-DC Controllers and Regulators · SOP-7

PN8034SSC-R1B from Wuxi Chipown Micro electronics, in a SOP-7. 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 GND power_in Ground / IC reference. Pins 1 and 2 are internally tied together as the chip ground return.
2 GND power_in Ground / IC reference. Pins 1 and 2 are internally tied together as the chip ground return.
3 VDD power_in Chip supply pin. Startup charge current ~2mA from internal HV startup; VDDon = 11.5V (typ), VDDoff = 9V (typ), VDD clamp = 20V (typ), abs-max 35V. VDD capacitor sets restart timing; place close to VDD/GND.
4 NC unconnected No-connect. May optionally be connected to the SW high-voltage pin for PCB routing convenience.
5 NC unconnected No-connect. May optionally be connected to the SW high-voltage pin for PCB routing convenience.
6 SW output Drain of the integrated 650V high-avalanche power MOSFET. Abs-max -0.3~650V; drain pulse current 3A (Tpulse=100us); RDS(on) = 8.0Ω typ (SOP-7). Connects to the buck/buck-boost inductor.
7 SW output Drain of the integrated 650V high-avalanche power MOSFET. Pins 6 and 7 are internally tied together to share current and improve thermal dissipation.
