FM9920D
Shenzhen Fuman · AC-DC Controllers & Regulators · SOP-8
FM9920D from Shenzhen Fuman, in a SOP-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 | GND | power_in | Source of the built-in synchronous rectifier MOSFET; pins 1, 2 and 3 must be connected together. |
| 2 | GND | power_in | Source of the built-in synchronous rectifier MOSFET; pins 1, 2 and 3 must be connected together. |
| 3 | GND | power_in | Chip ground; pins 1, 2 and 3 must be connected together. |
| 4 | VCC | power_in | Chip supply pin, charged from the output through the D pin; absolute maximum is -0.3 V to 7 V, start-up threshold 3.3 V and undervoltage lockout 2.9 V. |
| 5 | D | passive | Drain of the built-in synchronous rectifier MOSFET, absolute maximum -0.3 V to 45 V; it also supplies the chip operating current to VCC, and added copper area is recommended for heat dissipation. |
| 6 | D | passive | Drain of the built-in synchronous rectifier MOSFET, absolute maximum -0.3 V to 45 V; it also supplies the chip operating current to VCC, and added copper area is recommended for heat dissipation. |
| 7 | D | passive | Drain of the built-in synchronous rectifier MOSFET, absolute maximum -0.3 V to 45 V; it also supplies the chip operating current to VCC, and added copper area is recommended for heat dissipation. |
| 8 | D | passive | Drain of the built-in synchronous rectifier MOSFET, absolute maximum -0.3 V to 45 V; it also supplies the chip operating current to VCC, and added copper area is recommended for heat dissipation. |
