It is patible with SAMA5DX and SAM9X6 MPUs, which are supported by dedicated device variants that optimize the solution BOM. The MCP16502 integrates four DC-DC Buck regulators and two auxiliary LDOs, and provides a prehensive interface to the MPU, which includes an interrupt flag and a 1 MHz I2C interface. All Buck channels can support loads up to 1A and are 100% duty cycle-capable. Two 300 m A LDOs are provided such that sensitive analog loads can be supported. The DDR memory voltage (Buck2...
