AP4470 Datasheet (AKM) - Ultra-Low Power Step-up DC/DC Converter

AP4470, Ultra-Low Power Step-up DC/DC Converter

The AP4470 is an ultra-low consumption power management chip that integrates a step-up DC/DC converter and hysteresis comparators.

The AP4470 requires only 0.20V input to start boosting without the need for an external transformer.

The AP4470 has hysteresis operation switch that can control the pow
