RY9122

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).
