30V Buck-Boost Charger with Integrated MOSFETs and OTG

Overview

TopologyBuck-Boost Converter
Input voltage4-29 V
Switching frequency125-1000 kHz
Output 18.4 V / 3 A
IC revision0.0

Description

The ACT2861 is a buck-boost charger with 4 integrated MOSFETs. It offers a high efficiency, low component count, compact solution for 2 to 5 cell battery charging application. It operates from an input voltage range from 4 to 29V. An advanced switch control algorithm allows the buck-boost converter to maintain output voltage regulation with input voltages that are above, below or equal to the output voltage. The ACT2861 is optimized to reduce input current in shipping, shutdown, and standby for applications which are sensitive to quiescent current draw, such as battery-powered devices. The system can be monitored and configured by I²C. The built-in ADC can be read for the information of input/output voltages and currents, and the die temperature. With an MCU, it can easily be configured to charge a multi cell battery pack from a variety of input power sources.

Features

  • Buck-Boost Charger with Integrated FETs
  • Input Voltage Range: 4 to 29V (No Dead Zone)
  • Supports 2 to 5 series cell battery packs
  • Seamless Transition Between Buck and Boost Mode
  • OTG output supports QC3.0 / USB PD + PPS
  • 2V ~ 5V/100mA Programmable Output LDO
  • <5 μA Battery Leakage Current in Ship Mode
  • Voltage and Current monitoring
  • Thermal Regulation and Protection
  • JEITA Compliant
  • Programmable via I²C or Standalone
  • Thermally Enhanced 32-Lead 4mx4mm QFN

Typical applications

  • Multiple Power Source Supplies / DC UPS
  • Solid-State Lighting
  • Solar Powered Devices
  • Automotive Power Systems
  • Portable Battery-Powered Devices
  • Multi Cell Battery Charger / Car Charger / Power Bank
  • 24V Industrial Applications
