MCP16501TB-E/RMB [Microchip]

The MCP16501 integrates three DC-DC Buck regulators and one auxiliary LDO, providing a comprehensive interface to the MPU. All Buck channels support loads up to 1A and are 100% duty cycle-capable. The 300 mA LDO supports sensitive analog loads. DDR memory voltage (Buck2 output) and MPU core voltage (Buck3 output) are selectable via three-state input pins, eliminating external feedback resistor inaccuracies. Default power channel sequencing is built-in per MPU requirements. Features include low no-load operational quiescent current, active discharge resistors on each output, safe start-up into pre-biased outputs, thermal shutdown, current limit protection, and automotive AEC-Q100 reliability. Packaged in a 24-pin 4x4mm VQFN package.
