Description

The ACE7268N is a high efficiency 1MHz synchronous step-down DC-DC converter capable of

delivering 3A current. The ACE7268N operates over a wide input voltage range from 4.5V to 18V and

Low output voltage ripple and small external inductor and capacitor sizes are achieved with 1MHz

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

step down applications.
