Description
The ACE72224Y is high-efficiency, high frequency synchronous step-down DC-DC regulator ICs
capable of delivering up to 2A output currents. The ACE72224Y family operate over a wide input voltage
range from 4.5V to 24V and integrate main switch and synchronous switch with very low RDS(ON) to
minimize the conduction loss.
ACE72224Y adopts the pure COT architecture to achieve fast transient responses for high step-down
applications. In addition. The ACE72224Y is stable with extremely low ESR, high capacitance.
ACE72224Y always operate in continuous conduction mode, which reduces the output ripple voltage in
light load compared to discontinuous conduction mode.
