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

General Description

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.

Key Features

  •  Startup voltage : Cold start from 0.20V typical  DC/DC switching frequency : 60kHz typical at VIN=0.4V  Operation Voltage : up to 1.0V (VIN) up to 5.5V (VDD1 / VDD2) Operation temperature : -30 ~ +85ºC  Power Consumption DC/DC converter is active : 7A typical at VIN=0.4V DC/DC converter is off : 0.5A typical at VIN=0.4V (The AP4470 supplies power including over charge protection current)  DC/DC active indicator  Power Good indicator  DC/DC disable function  On-ch.

[AP4470] AP4470 Ultra-Low Power Step-up DC/DC Converter for Energy Harvesting Applications 1. General Description 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 power supply for target devices (sensors, wireless modules, LEDs) while protecting external storage (capacitors), and the target. 1μW DC input is enough to startup the AP4470. Converted output is stored to external storage device and the AP4470 monitors the device. When the voltage of external storage reaches 3.
