Descriptions

The DIO6100 is high-efficiency, high frequency

synchronous step-down DC-DC regulator ICs

capable of delivering up to 1A output currents.

The DIO6100 family operate over a wide input

voltage range from 2.5V to 5.5V and integrate

main switch and synchronous switch with very

low RDS(ON) to minimize the conduction loss.

Low output voltage ripple and small external

inductor and capacitor sizes are achieved with

greater than 1.5MHz switching frequency.
