TPS16630PWPR from Texas Instruments, in a HTSSOP-20. 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 | IN | power_in | Power supply input connected to the drain of the internal FET. |
| 2 | IN | power_in | Power supply input connected to the drain of the internal FET. |
| 3 | IN | power_in | Power supply input connected to the drain of the internal FET. |
| 4 | N.C | unconnected | No connection. |
| 5 | N.C | unconnected | No connection. |
| 6 | P_IN | power_in | Device power supply voltage; always connect P_IN directly to IN. |
| 7 | UVLO | input | Programmable undervoltage lockout input; undervoltage event shuts down internal FET and asserts FLT to indicate power fault. |
| 8 | OVP | input | Adjustable overvoltage protection threshold input (TPS16630 only); overvoltage event shuts down internal FET and asserts FLT to indicate overvoltage fault. |
| 9 | GND | power_in | Ground connection to system ground. |
| 10 | dVdT | bidirectional | Output voltage slew rate control; capacitor to GND sets slew rate; leave floating for maximum slew rate enabling thermal regulation during power-up. |
| 11 | ILIM | bidirectional | Current limit programming input; resistor to GND sets overload current limit from 0.6 A to 6 A with ±7% accuracy. |
| 12 | MODE | input | Mode selection pin for overload fault response; open circuit for latch mode, shorted to GND for auto-retry mode. |
| 13 | SHDN | input | Shutdown control input; pull below 0.8 V for low-power shutdown, above 2 V for enable; cycling resets latched faults. |
| 14 | IMON | output | Analog current monitor output with ±6% accuracy proportional to output current; resistor to GND converts current to voltage with 27.9 µA/A gain. |
| 15 | FLT | output | Fault indicator open-drain output (active-low); asserted on undervoltage, overvoltage, overcurrent, power limit, or thermal fault conditions. |
| 16 | PGOOD | output | Power good indicator open-drain output (active-high); high when internal FET is enhanced, low when off or SHDN pulled low. |
| 17 | N.C | unconnected | No connection. |
| 18 | OUT | power_out | Power output from internal FET source with 31 mΩ on-resistance rating; rated for 6 A maximum load current. |
| 19 | OUT | power_out | Power output from internal FET source with 31 mΩ on-resistance rating; rated for 6 A maximum load current. |
| 20 | OUT | power_out | Power output from internal FET source with 31 mΩ on-resistance rating; rated for 6 A maximum load current. |

Package_SO:TSSOP-20-1EP_4.4x6.5mm_P0.65mm_EP2.15x3.35mm - 3D model: HTSSOP-20, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 1.2 mm nominal TSSOP height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
