RY9120

RYCHIP · DC-DC Converters · SOT-23-6

RY9120 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 passive Bootstrap pin: a capacitor connected between SW and the BST pin is required to form a floating supply across the high-side switch driver.
2 GND power_in Ground pin for the device.
3 FB input Adjustable-version feedback input; connect to the center point of the external resistor divider, with VFB of 0.585V min, 0.6V typ, 0.615V max.
4 EN input Drive to logic-high to enable the IC and to logic-low to disable it into micro-power shutdown; the EN rising threshold is 1.4V and the falling threshold is 0.8V.
5 IN power_in Power supply pin; the input voltage range is 4.5V to 17V, with an absolute maximum of 18V.
6 SW output Switching pin, the output of the internal power MOSFETs; absolute maximum SW voltage is -3V to 19V (-5V to 19V for transients under 10 ns).
