MIC33163/4 4MHz, 1A, Buck Regulator with Integrated Inductor and HyperLight Load® General Description The MIC33163/4 is a highly-efficient synchronous buck regulator with integrated inductor which provides the optimal trade-off between footprint and efficiency. The MIC33163/4 operates at 4MHz switching frequency and provides up to 1A output current. In addition, the 100% duty cycle and HyperLight Load® (HLL) mode-of-operation delivers very-high efficiency at light loads and ultra-fast transient response which makes the MIC33163/4 perfectly suited for any space constrained application and great alternative for low dropout regulators.
