Pin Definitions

Pin Name

Description

FB

Feedback. An external resistor divider from the output to GND tapped to FB sets the output

voltage.

GND

Power ground.

VIN

Supply voltage. The DIO6905C operates from a 2.3 V to 5.5 V unregulated input. A decoupling

capacitor is required to prevent large voltage spikes from appearing at the input.

SW

Output switching node. SW is the drain of the internal high-side P-channel MOSFET. Connect

the inductor to SW to complete the converter.

EN

On/off control.

OUT

Output voltage power rail and input sense for the output voltage. Connect the load to OUT.

An output capacitor is required to decrease the output voltage ripple.
