DESCRIPTION

The A7332 integrated synchronous rectified stepdown

converter that provides wide 4.2V to 28V

input voltage range and 3A continuous load current

capability.

The A7332 operates at PFM mode to achieve high

efficiency and reduce power loss at light load. In

shutdown mode, the Max supply current is about

3μA.

The A7332 has protection function includes cycleby-

cycle current limit, UVLO and thermal

shutdown. Internal soft-start prevents inrush

current at fast power-on. The A7332 uses slope

compensated current mode control which provides

fast load transient response. Internal loop

compensation function reduces the external

compensator components and simplifies the

design process.

The A7332 is available in PSOP8 package.
