Universal input reference design for 12-V lead acid battery charger

Overview

TopologyFlyback Converter
Input voltage85-265 V
Switching frequency0.88-94 kHz
Output 114 V / 2.5 A
IC revisionA

Description

This reference design takes a Universal AC input (85 VAC - 265 VAC) and converts to a 17.5-V isolated output using a PSR flyback topology. It is then followed by a battery charger circuit, which outputs up to 15 V to a lead acid battery. This is a fast-charge design capable of delivering 12 V @ 2.5 A (30 W) to the battery.

Features

  • Universal input (85 VAC - 265 VAC), which can be used to power up the charger worldwide
  • Conducted EMI testing provided
  • Primary side regulated (PSR) flyback topology provides a cost-effective solution
  • Small form factor to fit any mechanical housing of typical battery chargers

Typical applications

  • Low Power AC to DC SMPS
  • USB Type-C AC Adapters for Consumer Electronics
  • Industrial and Medical SMPS
  • Adapters and Chargers for Phones and Tablets
