Microchip Technology EV93M52A MIC21LV33 Evaluation Board

Microchip Technology EV93M52A MIC21LV33 Evaluation Board is designed to demonstrate the functionality and versatility of the MIC21LV33 quickly. The MIC21LV33 is a constant on-time, dual-phase synchronous buck controller featuring a unique adaptive ON-time control architecture with Hyperlight load and phase shedding features enabled. The MIC21LV33 is used with external MOSFETs and output filters to implement dual phase single output, high current switch mode power supply.

The Microchip EV93M52A Board is based on a buck topology and provides an adjustable output voltage between 0.6 and 28V. The board offers a maximum current of 50A when supplied with 4.5V to 36V at the input. Furthermore, the board is tuned and optimized for a 0.82V/40A output.
