TP5610B from TPOWER, in a ESOP-8. 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 | BST | passive | Supplies the internal high-side power switch driver and connects through a bootstrap capacitor of 68nF to 100nF to the SW pin, which should be placed as close to the chip as possible. |
| 2 | VIN | power_in | Chip supply input with a rated range of -0.3 V to +36 V (absolute maximum), a recommended operating range of 9 V to 30 V, and a input overvoltage protection threshold of 30 V; a bypass capacitor to ground is required. |
| 3 | SW | output | Internal power switch output node that drives the inductor, rated from -0.7 V to VVIN+0.3 V. |
| 4 | PGND | power_in | Chip power ground, which carries the high-current return path of the converter. |
| 5 | GND | power_in | Chip signal ground for the control circuitry, rated for the same -0.3 V to +6 V reference as the other low-voltage pins. |
| 6 | FB | input | Error amplifier feedback input that sets the output voltage through a resistor divider referenced to the 1 V (typical) FB threshold, with R2 recommended below 30 kΩ and a rating of -0.3 V to +6 V. |
| 7 | SNS | input | Output constant-current sense input, where a resistor to ground sets the output current against a 75 mV (typical) reference threshold, with a rating of -0.3 V to +6 V. |
| 8 | EN | input | Chip enable input where logic high (2.5 V minimum) enables switching and logic low (0.6 V maximum) puts the chip in standby, with an internal 200 kΩ pull-up and a rating of -0.3 V to +6 V. |
| 9 | Exposed PAD | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
