AP4470 Datasheet Ultra-low Power Step-up DC/dc Converter

Manufacturer: AKM (Asahi Kasei Microdevices)

Overview: [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.

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.
