Description

The ACE7212Y is high-efficiency, high frequency synchronous step-down DC-DC regulator ICs

capable of delivering up to 2A continuous output currents. The ACE7212Y family operate over a wide

input voltage range from 4.5V to 24V and integrate main switch and synchronous switch with very low

ACE7212Y adopts the COT architecture to achieve fast transient responses for high step-down

applications and high efficiency at light loads. In addition, it operates at pseudo-constant frequency of

500kHz under heavy load conditions to minimize the size of inductor and capacitor.
