Microchip Technology MCP16501 Cost & Size Optimized PMIC
Microchip Technology MCP16501 Cost & Size Optimized PMIC is compatible with the latest Microchip Microprocessor Units (MPU) and associated DRAM Memories. The SAMA5, SAM9X60, and SAMA7G54 series MPUs are supported by dedicated PMIC variants. They are programmed for the different supply voltages and power sequencing requirements. The MCP16501 integrates three DC-DC Buck regulators and one auxiliary LDO. It provides a comprehensive interface to the MPU. All Buck channels can support loads up to 1A and are 100% duty cycle capable.
