Ultra-Low Power Step-up DC-DC Converter

The AP4473 is an ultra-low consumption power management chip that integrated a step-up DC-DC converter and hysteresis comparators. The AP4473 requires only 15mV (typical) input to start boosting using an external transformer. The AP4473 has hysteresis operation switch that can control the power supp
