The MIC5209YM is a highly-integrated, low noise, fixed frequency, synchronous, buck regulator from Microchip. It features an integrated high-side power switch and low-side power switch, which reduces component count and board space compared to traditional buck regulator designs. It is designed to operate from input voltages between 4.5V to 38V and provides adjustable output voltages down to 0.8V. The MIC5209YM utilizes a proprietary topology and on-chip compensation, delivering up to 8A of output current with high efficiency, up to 95%. It includes a wide range of protection features, such as under voltage lockout, over voltage protection, cycle-by-cycle current limit, overtemperature shutdown, overtemperature warning, and more.
