MCP16321 EVALUATION BOARD

This product is no longer available for sale.

The MCP16321 is a highly integrated, 1A output current capable, high-efficiency, fixed-frequency, synchronous, step-down DC-DC converter in a popular 3 mm x 3 mm 16-lead QFN package that operates from input voltage sources up to 24V. Integrated features include a low resistance high-side switch, low resistance low-side switch, 1.0 MHz fixed-frequency Peak-Current mode control, internal compensation, power good output, peak current limit, VOUT overvoltage and overtemperature protection. Minimal external components are necessary to develop a complete step-down DC-DC converter power supply. The MCP16321 draws less than 10 µA while disabled. High converter efficiency is achieved by integrating the current-limited, low-resistance, high-speed N-Channel MOSFETs and associated drive circuitry. Incorporating both the upper and lower switches reduces the need for external components. High switching frequency minimizes the size of external filtering components, resulting in an overall small solution size
