RYCHIP · DC-DC Converters · SOT-23-6
RY9122 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 | GND | power_in | Ground pin; the datasheet recommends a large copper area on GND to cool the chip and improve thermal performance. |
| 2 | SW | output | Switching node between the internal high-side and low-side power MOSFETs; the datasheet limits SW voltage to -0.3V to (VIN+0.5V). |
| 3 | IN | power_in | Power supply input for the regulator, rated for 4V to 18V operation with an absolute maximum of 20V on VIN and EN; bypass ceramic capacitors should be placed close to this pin. |
| 4 | FB | input | Adjustable-version feedback input that connects to the center point of the external resistor divider; the internal reference is 0.8V and FB is rated -0.3V to 6V. |
| 5 | EN | input | Enable input: drive to logic-high to enable the IC and to logic-low to disable it and enter micro-power shutdown; absolute maximum is -0.3V to 20V. |
| 6 | BS | passive | Bootstrap pin; a capacitor connected between SW and BS is required to form the floating supply for the high-side switch driver, with VBS limited to (VSW-0.3V) to (VSW+5V). |
