RT6206AHGSP

Richtek Tech · DC-DC Converters · SOP-8-EP

RT6206AHGSP from Richtek Tech, in a SOP-8-EP. 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 EN input Enable control input; logic-high (>2V, up to 18V) enables the converter and logic-low (<0.4V) forces shutdown with supply current below 10µA.
2 FB input Feedback voltage input that regulates the output via an external resistive divider, with a typical feedback threshold of 0.765V.
3 VREG5 power_out Internal regulator output (5.1V typ.); connect a 1µF capacitor to GND to stabilize the output voltage.
4 SS passive Soft-start time setting pin; connect an external capacitor between this pin and GND to set the soft-start time.
5 PGND power_in Power ground; connect to the PCB ground plane.
6 SW power_out Switch node; connect this pin to an external L-C filter.
7 BOOT passive Bootstrap supply for the high side gate driver; connect a 0.1µF capacitor between the BOOT and SW pins.
8 VIN power_in Power input with a 4.5V to 18V range; must be bypassed with a suitably large (10µF x 2) ceramic capacitor.
9 PGND power_in Exposed pad, power ground; must be soldered to a large PCB area and connected to PGND for maximum power dissipation.
