Fast Charge Adapter Solution with 3.5-5.5V 7A Output Reference Design

Overview

TopologyFlyback Converter
Input voltage85-265 V
Output 15.5 V / 7 A
IC revisionE1

Description

The PMP40060 is a fast charger solution with secondary-side regulation UCC28740DR which provides Constant-Voltage Constant-Current feature. The design supports 3.5V 7A lower output voltage closely to battery voltage and also 5.5V 7A output power level. This output performance will enable direct charge between PMP40060 and PMP40133 (adapter side) and BQ25871 EVM (phone side). Secondary voltage-second balance synchronous rectifier UCC24636 enables high efficiency with maximum SR conduction time.

Features

  • Valley switching operation and VS balance S.R flyback
  • System level solution for cable impedance detection and BAT OVP co-working with BQ2587x
  • 5V2A normal output and compliant with TI fast charge through D+/D-
  • One or two type-C optional
  • Vbus adjustable with 10mV/step resolution

Typical applications

  • Fast Charge Adapter
