Description

The ACE7224Y is high-efficiency, high frequency synchronous step-down DC-DC regulator ICs

capable of delivering up to 3A output currents. The ACE7224Y family operate over a wide input voltage

minimize the conduction loss.

The pure COT architecture with Pseudo fixed switching frequency operation provides fast transient

response and eases loop stabilization. Protection features include over-current protection and thermal

shutdown.

ACE7224Y always operate in continuous conduction mode, which reduces the output ripple voltage in

light load compared to discontinuous conduction mode. The ACE7224Y is stable with extremely low ESR,

high capacitance. The ACE7224Y requires a minimal number of readily-available, standard, external

components and is available in a space-saving TSOT23-6 package.
