4.2 MCP16501 PMIC

MCP16501 is a 4-channel PMIC designed for PCB area constrained applications. It features three 1A DC-DC Buck regulators and one 0.3A auxiliary LDO regulator, and provides a simple, leakage-free interface with SAMA7G5 Series. MCP16501 supports all SAMA7G5 Series low-power modes except ULP2, as VDDCPU is fed from the same power rail as VDDCORE. See the following figure.

  • MCP16501A supports systems based on DDR2 (1.8V) or DDR3L (1.35V) SDRAM memories.
  • MCP16501D supports applications using LPDDR2-SDRAM or LPDDR3-SDRAM. In this version, LOUT must be set at 1.8V and enabled by connecting LEN to OUT1.
