AP4470 Description
The AP4470 is an ultra-low consumption power management chip that integrates a step-up DC/DC converter and hysteresis parators. 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 power supply for target devices (sensors, wireless modules, LEDs) while protecting external storage (capacitors), and the...
