ACE7377N

High Efficiency, 3A, 23V, 500kHz Synchronous Step Down Regulator

VER 1.3

1

Description

The ACE7377N is a high efficiency 500 kHz synchronous step-down DC-DC converter capable of

delivering 3A current. The ACE7377N operates over a wide input voltage range from 4.5V to 23V and

integrates 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 500 kHz

switching frequency. It adopts the instant PWM architecture to achieve fast transient responses for high

step down applications
