TMF0265

TM Shenzhen Titan Micro Elec · AC-DC Controllers And Regulators · DIP-8

TMF0265 from TM Shenzhen Titan Micro Elec, in a DIP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VDD-G power_in Internal driver supply input that connects through a resistor to VDD; the datasheet gives no voltage limit for this pin.
2 VDD power_in Supply input with a recommended operating range of 10 to 23 V and an absolute maximum of 30 V.
3 FB input Voltage feedback pin driven from an external optocoupler, with a recommended input of 0 to 5 V and an absolute range of -0.3 to 6.0 V.
4 CS input Current sense pin connected to the power MOSFET source and an external sense resistor, with an input range of -0.3 to 5.0 V.
5 DRAIN passive Drain of the integrated power MOSFET, which the datasheet rates at a minimum drain-source breakdown voltage (BVDSS) of 650 V.
6 DRAIN passive Drain of the integrated power MOSFET, which the datasheet rates at a minimum drain-source breakdown voltage (BVDSS) of 650 V.
7 GND power_in Ground pin for the controller, referenced to the system ground.
8 GND power_in Ground pin for the controller, referenced to the system ground.
