A7335

DC-DC CONVERTER BUCK (STEP-DOWN)

30V, 3.5A SYNCHRONOUS CV/CC

DESCRIPTION

FEATURES

A7335 is a wide input voltage, high efficiency

Synchronous CC/CV step-down DC/DC converter

that operates in either CV (Constant Output Voltage)

mode or CC (Constant Output Current) mode. A7335

provides up to 3.5A output current at EMI friendly

133kHz switching frequency. For >3.0A loading

current, it is advised to add an optional external

power Schottky Diode D1 to relieve partial heat

dissipation as drawn in application diagram. A7335

eliminates the expensive, high accuracy current

sensing resistor, making it an ideal CC charger for

battery charging applications and adaptors with

accurate current limit. The A7335 achieves higher

efficiency than traditional constant current switching

regulators by eliminating its associated power loss on

the additional current sensing resistor.
