Texas Instruments · DC-DC Converters · WQFN-24-EP(4x4)
LP3907SQ-TJXIP from Texas Instruments, in a WQFN-24-EP(4x4). 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 | VINLDO12 | power_in | Analog power for internal functions (VREF, BIAS, I2C, logic) of the LP3907. |
| 2 | EN_T | input | Enable input for the preset power-on sequence. |
| 3 | nPOR | output | Open-drain power-on reset output for Buck1 and Buck2 with a 100-kΩ pullup resistor, pulled to ground when these supplies are not good. |
| 4 | GND_SW1 | power_in | Buck1 NMOS power ground. |
| 5 | SW1 | power_out | Buck1 switcher output pin. |
| 6 | VIN1 | power_in | Power input from a DC source or battery to Buck1. |
| 7 | ENSW1 | input | Enable pin for Buck1; a logic HIGH enables Buck1. |
| 8 | FB1 | input | Buck1 feedback input terminal. |
| 9 | GND_C | power_in | Non-switching core ground pin. |
| 10 | AVDD | power_in | Analog power for the Buck converters. |
| 11 | FB2 | input | Buck2 feedback input terminal. |
| 12 | ENSW2 | input | Enable pin for Buck2; a logic HIGH enables Buck2. |
| 13 | VIN2 | power_in | Power input from a DC source or battery to Buck2. |
| 14 | SW2 | power_out | Buck2 switcher output pin. |
| 15 | GND_SW2 | power_in | Buck2 NMOS power ground. |
| 16 | SDA | bidirectional | I2C data line (bidirectional). |
| 17 | SCL | input | I2C clock input. |
| 18 | GND_L | power_in | LDO ground. |
| 19 | VINLDO1 | power_in | Power input from a DC source or battery to the input terminal of LDO1. |
| 20 | LDO1 | power_out | LDO1 regulator output. |
| 21 | ENLDO1 | input | LDO1 enable pin; a logic HIGH enables LDO1. |
| 22 | ENLDO2 | input | LDO2 enable pin; a logic HIGH enables LDO2. |
| 23 | LDO2 | power_out | LDO2 regulator output. |
| 24 | VINLDO2 | power_in | Power input from a DC source or battery to the input terminal of LDO2. |
| 25 | DAP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
