Descriptions
The DIO6012 is high-efficiency, high frequency
synchronous step-down DC-DC regulator ICs
capable of delivering up to 2 A output currents.
The DIO6012 family operate over a wide input
voltage range from 2.7 V to 5.5 V 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 MHz switching frequency.
