TPS259251DRCR from Texas Instruments, in a VSON-10-EP(3x3). Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | dV/dT | output | Output voltage slew-rate control pin. Connect a capacitor (1 nF to 1000 nF recommended) from this pin to GND to program the OUT ramp rate at device turn-on. dV/dT-to-OUT gain is approximately 4.85 V/V; max capacitor voltage 5.5 V. |
| 2 | EN/UVLO | input | Dual-function enable / programmable UVLO input. Pulling below the EN falling threshold (~1.35 V) shuts off the internal pass MOSFET; pulling above the EN rising threshold (~1.4 V) enables the device. An external resistor divider from VIN sets the UVLO trip point. Absolute max 7 V, recommended 0-6 V. |
| 3 | VIN | power_in | Input supply voltage. Recommended 4.5-5.5 V for TPS25925x variants (absolute max 20 V, 22 V transient). Pins 3, 4, 5 are internally tied together and must all be connected to the input rail. |
| 4 | VIN | power_in | Input supply voltage (paralleled with pins 3 and 5). Tie all VIN pins together for current handling. |
| 5 | VIN | power_in | Input supply voltage (paralleled with pins 3 and 4). Tie all VIN pins together for current handling. |
| 6 | OUT | power_out | Protected output of the internal 30-mΩ pass MOSFET. Pins 6, 7, 8 are internally tied and should all be connected together. Recommended external output capacitance 0.1 µF to 1000 µF; continuous current up to 5 A. |
| 7 | OUT | power_out | Protected device output (paralleled with pins 6 and 8). Tie all OUT pins together. |
| 8 | OUT | power_out | Protected device output (paralleled with pins 6 and 7). Tie all OUT pins together. |
| 9 | NC | unconnected | Not connected internally. May be left floating or tied to GND. |
| 10 | ILIM | output | Current-limit programming pin. A resistor (R_ILIM = 10-162 kΩ recommended) from this pin to GND sets the overload / short-circuit current limit (typ 5.1 A at 150 kΩ, 3.75 A at 100 kΩ, 2.1 A at 45.3 kΩ, ±15% accuracy). ILIM bias current ~10 µA; absolute max 7 V. |
| 11 | GND | power_in | Exposed thermal pad on the bottom of the VSON package. Serves as the device ground reference AND primary thermal path; must be soldered to the PCB ground plane for proper electrical and thermal operation. |
