描述 Description

The ACE73100N develops a high efficiency, current mode adaptive constant off time controlled,

asynchronous step-down DC/DC converter capable of delivering 3A output current. The ACE73100N

operates over a wide input voltage range from 4.5V to 100V and integrates main switch with very low

RDS(ON) to minimize the conduction loss. The switching frequency is adjustable from 100kHz to 500kHz

using an external resistor. And the device features cycle-by-cycle peak current limitation.
