AP6502A
240kHz 23V 2A SYNCHRONOUS DC/DC BUCK CONVERTER
Description
The AP6502A is a 240kHz switching frequency external compensated
synchronous DCDC buck converter. It has integrated low R
DSON
high
and low side MOSFETs.
The AP6502A enables continues load current of up to 2A with efficiency
as high as 95%.
The AP6502A features current mode control operation, which enables
fast transient response times and easy loop stabilization.
The AP6502A simplifies board layout and reduces space requirements
with its high level of integration and minimal need for external
components, making it ideal for distributed power architectures.
The AP6502A is available in a standard Green SO-8EP package with
an exposed PAD for improved thermal performance and is RoHS
compliant.
