RT6150BGQW

Richtek Tech · DC-DC Converters · WSON-10-EP(2.5x2.5)

RT6150BGQW from Richtek Tech, in a WSON-10-EP(2.5x2.5). 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 VOUT power_out Output of the Buck-Boost converter; connect a capacitor between VOUT and GND.
2 LX2 passive Second switch node; connect this pin to the inductor.
3 GND power_in Power ground; the exposed pad must be soldered to a large PCB and connected to GND for maximum power dissipation.
4 LX1 passive First switch node; connect this pin to the inductor.
5 VIN power_in Power input; connect an at least 10µF capacitor between VIN and GND.
6 EN input Enable control input for the Buck-Boost converter; EN high starts operation with soft-start and EN low shuts the device down.
7 PS input PSM control input; pull low for PSM operation and pull high for fixed-frequency operation.
8 VINA power_in Supply voltage input for the control circuit; UVLO requires VINA above 1.65V to enable the converter.
9 GND power_in Power ground, one of three GND pins that must connect to the common ground.
10 FB input Feedback input; for adjustable versions connect a resistive divider (output adjustable from 1.8V to 5.5V), and for the fixed version it must be connected to VOUT.
11 GND power_in Power ground, one of three GND pins; the exposed pad must be soldered to a large PCB and connected to GND for maximum power dissipation.
