AP6503SP-13

AP6503 340kHz 23V 3A SYNCHRONOUS DC/DC BUCK CONVERTER Description Pin Assignments The AP6503 is a 340kHz switching frequency external compensated synchronous DC-DC buck converter. It has integrated low RDSON high ( Top View ) and low side MOSFETs. The AP6503 enables continuous load current of up to 3A with efficiency as high as 95%. The AP6503 features current mode control operation, which enables fast transient response times and easy loop stabilization. The AP6503 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.
