4.1 MCP16502 PMIC
MCP16502 is a 6-channel PMIC supporting high-performance applications requiring Digital Voltage Scaling.
MCP16502 features four 1A DC-DC Buck regulators and two 0.3A auxiliary LDO regulators, and provides a comprehensive interface to the MPU, which includes an interrupt flag and a 1-MHz I²C interface.
The PMIC-processor interface is optimized so that it remains leakage-free in any power mode. MCP16502 supports all SAMA7G5 Series low-power modes. Although MCP16502 power states are fully programmable through its I²C interface, they are entered and/or exited on pin level change to ease software operations. See the following figure.
- MCP16502AB supports systems based on DDR2 (1.8V) or DDR3L (1.35V) SDRAM memories.
- MCP16502AD supports applications using LPDDR2-SDRAM or LPDDR3-SDRAM. In this version, LOUT2 is started at 1.8V.
