FP6373A
High Efficiency 1MHz853AT
Synchronous Step Down
Regulator
Description
The FP6373A is a high-efficiency 1MHz synchronous step-down DC-DC
regulator and capable of delivering output current up to 3A.
The FP6373A operates over wide input voltage range from 2.
7V to 5.
5V, and integrates main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss.
Low output voltage ripple, small external inductor and capacitor sizes are achieved with 1MHz switching frequency.
