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. |
