VIPER265KDTR from STMicroelectronics, in a SOP-16. 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 | GND | power_in | Ground connected to the source of the internal power MOSFET and the controller ground reference. |
| 2 | N.C. | unconnected | Not internally connected; highly recommended to connect to GND (pin 1) or leave floating. |
| 3 | N.C. | unconnected | Not internally connected; highly recommended to connect to GND (pin 1) or leave floating. |
| 4 | N.A. | unconnected | Not available for user; mechanically connected to the controller die pad, and highly recommended to connect to GND (pin 1) to improve noise immunity. |
| 5 | VCC | power_in | Supply voltage of the control section; this pin provides the charging current of the external capacitor. |
| 6 | N.C. | unconnected | Not available for user; highly recommended to connect to GND (pin 1). |
| 7 | FB | input | Inverting input of the internal transconductance error amplifier; a single resistor to the converter output gives an output equal to the error amplifier reference voltage, and an external resistor divider is required for higher output voltages. |
| 8 | COMP | output | Output of the internal transconductance error amplifier; the compensation network goes between this pin and GND, with linear voltage range from VCOMPL to VCOMPH, and it can directly control the PWM with an optocoupler. |
| 9 | N.C. | unconnected | Not internally connected; can be connected to GND or left floating. |
| 10 | N.C. | unconnected | Not internally connected; can be connected to GND or left floating. |
| 11 | N.C. | unconnected | Not internally connected; can be connected to GND or left floating. |
| 12 | N.C. | unconnected | Not internally connected; can be connected to GND or left floating. |
| 13 | DRAIN | passive | High voltage drain pin from which the built-in high voltage switched start-up bias current is drawn; connected to the metal frame to help heat dissipation, so a PCB copper area is required. |
| 14 | DRAIN | passive | High voltage drain pin from which the built-in high voltage switched start-up bias current is drawn; connected to the metal frame to help heat dissipation, so a PCB copper area is required. |
| 15 | DRAIN | passive | High voltage drain pin from which the built-in high voltage switched start-up bias current is drawn; connected to the metal frame to help heat dissipation, so a PCB copper area is required. |
| 16 | DRAIN | passive | High voltage drain pin from which the built-in high voltage switched start-up bias current is drawn; connected to the metal frame to help heat dissipation, so a PCB copper area is required. |
