TPS54383PWPR 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 | PVDD1 | power_in | Power input to the Output 1 high-side MOSFET; bypass locally to GND with 10-μF or greater low-ESR ceramic capacitor. |
| 2 | BOOT1 | input | Gate driver supply input for Output 1; connect 22-nF to 82-nF capacitor from this pin to SW1, charged from BP through internal switch during converter OFF time. |
| 3 | SW1 | output | Switching output (source) for Output 1 PWM; a snubber is recommended to reduce ringing on this node. |
| 4 | GND | power_in | Ground pin for the device; connect directly to Thermal Pad. |
| 5 | EN1 | input | Active-low enable input for Output 1; disables above 1.55V, enables below 0.9V, driven to PVDD2 when floating; connect to GND for always-ON operation. |
| 6 | EN2 | input | Active-low enable input for Output 2; disables above 1.55V, enables below 0.9V, driven to PVDD2 when floating; connect to GND for always-ON operation. |
| 7 | FB1 | input | Feedback input for Output 1; internal error amplifier regulates this pin to 0.8-V reference through external resistor divider from output to ground. |
| 8 | FB2 | input | Feedback input for Output 2; internal error amplifier regulates this pin to 0.8-V reference through external resistor divider from output to ground. |
| 9 | ILIM2 | input | Current limit selection pin for Output 2 only; connection to BP sets 4.5A limit, floating sets 3.0A limit, GND sets 1.5A limit; includes internal 150-kΩ divider. |
| 10 | SEQ | input | Output startup sequencing control; connection to BP enables sequential mode (Output 1 slave), GND enables sequential mode (Output 2 slave), or floating for ratiometric startup; includes internal 150-kΩ divider. |
| 11 | BP | power_out | Regulated bootstrap supply output for gate drivers; internally generated 5.25-V supply; bypass to GND with 4.7-μF to 10-μF low-ESR ceramic capacitor. |
| 12 | SW2 | output | Switching output (source) for Output 2 PWM; a snubber is recommended to reduce ringing on this node. |
| 13 | BOOT2 | input | Gate driver supply input for Output 2; connect 22-nF to 82-nF capacitor from this pin to SW2, charged from BP through internal switch during converter OFF time. |
| 14 | PVDD2 | power_in | Power input to device control circuitry, EN1/EN2 pull-up driver, and Output 2 high-side MOSFET; bypass to GND with 10-μF or greater low-ESR ceramic capacitor; UVLO monitors this pin and enables device above 4.1V. |
| 15 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
