Microchip Technology MIC33M356
MIC33M356 is a I2C programmable, high-efficiency, low-voltage input, 3A current, synchronous step-down regulator power module with integrated inductor. The Constant On-Time (COT) control architecture with HyperLight Load® mode provides very high efficiency at light loads, while still having ultra-fast transient response. The I2C interface allows programming the output voltage between 0.6V and 1.28V, with 5 mV resolution or between 0.6V and 3.84V, with 10 mV and 20 mV resolution.FEATURES
