The AP65502 is a 500kHz switching frequency external compensated synchronous DC/DC buck converter. It has integrated low RDSON high and low side MOSFETs.
The AP65502 enables continues load current of up to 5A with efficiency as high as 96%.
The AP65502 implements an automatic custom light load efficiency improvement algorithm.
The AP65502 features current mode control operation, which enables fast transient response times and easy loop stabilization.
The AP65502 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 AP65502 is available in a standard Green SO-8EP package and is RoHS compliant.
