RT8259GJ6 from Richtek Tech, in a TSOT-23-6L. 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 | BOOT | passive | Bootstrap pin: a capacitor (10nF low-ESR ceramic per the application section) connects between BOOT and PHASE to form the floating supply for the high-side gate driver, with BOOT limited to VPHASE + 6V. |
| 2 | GND | power_in | Ground and voltage reference for the regulated output; it should be routed outside the D1-to-C1 ground path so switching current spikes do not couple noise into the part. |
| 3 | FB | input | Feedback input: an external resistor divider from VOUT to GND sets the output voltage using a 0.8V typical reference (0.784V to 0.816V), and the divider values also set loop bandwidth. |
| 4 | EN | input | Active-high chip enable with logic-high at 1.4V minimum and logic-low at 0.4V maximum, an allowed input range of 0V to 5.5V, and an internal pull-up to high when left open. |
| 5 | VIN | power_in | Supply input operating from 4.5V to 24V (26V absolute maximum), which should be bypassed to GND with a suitably large capacitor to limit voltage spikes. |
| 6 | PHASE | output | Switch output node of the internal power MOSFET, with a voltage range of -0.3V to (VIN + 0.3V), that should be kept small in area to limit high-frequency swing and noise. |
