Description

The AP65400 is a 340kHz switching frequency external compensated synchronous DC/DC buck converter. It has integrated low R_DSON high and low side MOSFETs.

The AP65400 enables continues load current of up to 4A with efficiency as high as 96%.

The AP65400 implements an automatic custom light load efficiency improvement algorithm.

The AP65400 features current mode control operation, which enables fast transient response times and easy loop stabilization.

The AP65400 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 AP65400 is available in a standard Green SO-8EP package and is RoHS compliant.
