TPS2141IPWPR from Texas Instruments, in a HTSSOP-14-EP. 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 | SW_PG | output | Power good signal for switch output, active high logic-level signal with no external pullup required. |
| 2 | SW_IN | power_in | Input to integrated N-channel MOSFET power switch, 2.7 V to 5.5 V supply voltage, 65 mΩ maximum on-state resistance. |
| 3 | SW_IN | power_in | Input to integrated N-channel MOSFET power switch, 2.7 V to 5.5 V supply voltage, 65 mΩ maximum on-state resistance. |
| 4 | LDO_IN | power_in | Input to LDO regulator, 2.7 V to 5.5 V supply voltage range. |
| 5 | SW_EN | input | Active-low enable signal for power switch on TPS2141 with internal pullup. |
| 6 | LDO_EN | input | Enable signal for LDO regulator, active high, no internal pullup or pulldown. |
| 7 | GND | power_in | Ground. |
| 8 | LDO_PG | output | Power good signal for LDO output, open-drain, active high. |
| 9 | ADJ | input | Feedback adjustment pin for LDO regulator to set output voltage from 0.9 V to 3.3 V adjustable. |
| 10 | LDO_PLDN | output | Open-drain output pulldown pin for LDO when connected to LDO_OUT to reduce fall time. |
| 11 | LDO_OUT | power_out | Output of LDO regulator, 250 mA continuous current, 0.5 V maximum dropout voltage, 0.9 V to 3.3 V adjustable. |
| 12 | SW_OUT | power_out | Output of switch, 500 mA continuous current rating with dual current limit, 100 mA initial and 1800 mA after 93% voltage rise. |
| 13 | SW_OUT | power_out | Output of switch, 500 mA continuous current rating with dual current limit, 100 mA initial and 1800 mA after 93% voltage rise. |
| 14 | SW_PLDN | output | Open-drain output pulldown pin for switch when connected to SW_OUT to reduce fall time. |
| 15 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
