FP6151XR-G1

Advanced Analog Technology · DC-DC Converters · SOP-8-EP

FP6151XR-G1 from Advanced Analog Technology, 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 SW output Switch node output of the internal power MOSFET; the boost capacitor is connected between SW and BS, and absolute maximum Vsw is VIN +0.3V.
2 EN input Enable/UVLO input; driving it to ground shuts the device down, EN input high is 1.5V minimum and low is 0.4V maximum, and UVLO rising threshold is 3.9V to 4.5V.
3 COMP output Error amplifier output for compensation; the compensation network connected here sets the control loop response.
4 FB input Feedback input connected to the resistive divider from the output; the feedback voltage is 0.808V typical (0.788V to 0.828V), and it is a sensitive node to keep away from SW.
5 GND power_in Ground return for the device.
6 RT input Resistor connection that sets the oscillator frequency; RT = 200kΩ gives 400kHz to 600kHz switching frequency.
7 VIN power_in Supply voltage input with a recommended range of 4.5V to 36V (absolute maximum -0.3V to 42V).
8 BS output Bootstrap output that drives the high-side gate through a capacitor connected between BS and SW; absolute maximum VBS is Vsw +6V.
9 EP power_in Exposed pad on the package bottom that must be connected to ground.
