Richtek Tech · DC-DC Converters · TSOT-23-8
RT7296FGJ8F from Richtek Tech, in a TSOT-23-8. 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 | PG | output | Power Good open-drain output that can be pulled up to PVCC through a resistor; it goes high after a 0.4 ms delay once the output reaches 90% of its normal voltage. |
| 2 | VIN | power_in | Power input supporting 4.5V to 17V, which must be bypassed with a suitable large ceramic capacitor at this pin. |
| 3 | SW | output | Switch node that connects to the external L-C filter. |
| 4 | GND | power_in | System ground. |
| 5 | BOOT | power_in | Bootstrap supply for the high-side gate driver; a 0.1 µF ceramic capacitor is connected between BOOT and SW. |
| 6 | EN/SYNC | input | Enable input (high = enable) that also accepts an external clock from 200 kHz to 2 MHz to set the switching frequency; with a pull-up resistor to VIN, the recommended value is 60k to 300k. |
| 7 | PVCC | power_out | 5V bias supply output that requires a minimum 0.1 µF capacitor to ground. |
| 8 | FB | input | Feedback voltage input that sets the output voltage through a resistive divider, with a feedback reference of 0.8V. |
