# RY9320AT6

**RYCHIP** · DC-DC Converters · SOT-23-6

RY9320AT6 from RYCHIP, in a SOT-23-6. 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 | BS | power_out | Bootstrap pin: a capacitor connected between SW and BST is required to form a floating supply across the high-side switch driver. |
| 2 | GND | power_in | Ground pin. |
| 3 | FB | input | Adjustable-version feedback input; connect FB to the center point of the external resistor divider. For the RY9320AT6 the feedback voltage is 0.600V typical (0.585V to 0.615V). |
| 4 | EN | input | Drive to a logic-high to enable the IC and to a logic-low to disable it and enter micro-power shutdown mode; EN rising threshold is 1.2V and falling threshold is 0.9V. |
| 5 | IN | power_in | Power supply pin; input voltage range is 4.5V to 28V. |
| 6 | SW | output | Switching pin; SW voltage is rated -0.3V to VIN+1V (-5V to VIN+2V for a 10ns transient). |
