MCP16501TA-E/RMB General Description

The MCP16501 is a cost and size optimized integrated PMIC, compatible with the latest Microchip’s Microprocessor Units (MPU) and associated DRAM Memories. The SAMA5, SAM9X60 and SAMA7G54 series MPUs are supported by dedicated PMIC variants programmed for the different supply voltages and power sequencing requirements.

The MCP16501 integrates three DC-DC Buck regulators and one auxiliary LDO, and provides a comprehensive interface to the MPU. All Buck channels can support loads up to 1A and are 100% duty cycle- capable. The 300 mA LDO is provided such that sensitive analog loads can be supported. The DDR memory voltage (Buck2 output) is selectable by means of a 3-state input pin. This method allows greater precision in the output voltage setting by eliminating inaccuracies due to external feedback resistors, while minimizing external component count. The voltage selection set allows easy migration across different generations of memory. The default power channel sequencing is built-in and configured to the requirements of the MPU. A dedicated pin (LPM) facilitates the transition to Low-Power modes and the implementation of Backup mode with DDR in self-refresh (Hibernate mode). The MCP16501 features a low no-load operational quiescent current and it draws less than 10 μA in full shutdown. Active discharge resistors are provided on each output. All Buck channels support safe start-up into pre-biased outputs.

The MCP16501 is available in a 24-pin 4 mm x 4 mm VQFN package with an operating junction temperature range from -40°C to +125°C.
