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.
