RY9430DP8

RYCHIP · DC-DC Converters · ESOP-8

RY9430DP8 from RYCHIP, in a ESOP-8. 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 BST passive Bootstrap pin: a capacitor connected between SW and BST is required to form a floating supply across the high-side switch driver.
2 VIN power_in Power supply pin with a recommended input range of 4.5V to 38V and an absolute maximum VIN voltage of 42V.
3 SW output Switching pin connecting the internal power MOSFETs to the inductor; SW is rated -0.3V to VIN+1V (-5V to VIN+2V for 10ns transients).
4 GND power_in Ground pin for the device, to be connected to a large copper area for thermal performance.
5 FB input Adjustable-version feedback input, connected to the center point of the external resistor divider; FB absolute maximum is 6V.
6 NC unconnected No connection.
7 EN input Enable input: drive logic-high to enable the IC and logic-low to disable it into micro-power shutdown; rising threshold is 1.1V and falling threshold is 0.9V, with an absolute maximum of 42V.
8 NC unconnected No connection.
9 EPAD power_in Exposed thermal pad, internally tied to GND; solder to a large copper area to cool the chip.
