NCP4371: 15 W HVDCP Quick Charge(TM) 3.0 Compatible CV/CC Charger

Overview

TopologyFlyback Converter
Input voltage90-265 V
Output 112 V / 2 A
IC revision1

Description

15 W HVDCPQuick Charge 3.0Compatible CV/CC ChargerThis design note describes a 15 W, universal AC mains,isolated Quasi-Resonant flyback converter compatible withQualcomm’s High Voltage Dedicated Charging Port QuickCharge 3.0 Class A specification. The converter providesadjustable output voltage in a range from 3.6 Vdc to 12 Vdc.It maintains maximum output power 15 W at full range ofthe voltage output and at same time it limits the maximumoutput current to 2.0 A. The design is targeted for smartphone and tablet charger applications.The charger design utilizes ON Semiconductor’s newNCP4371 Qualcomm Quick Charge 3.0 Controller,NCP1361E Quasi-Resonant Controller and NCP4305Synchronous Rectification controller.

Features

  • Universal AC Input Range (90–265 Vac).
  • Input Filter for Conducted EMI Attenuation
  • Very Low Standby and No-load Power Consumption
  • Quasi-Resonant Current Mode Control with ValleySwitching
  • Valley Lockout Avoids Audible Noise at ValleyJumping Operation
  • Secondary Synchronous Rectification Control for HighEfficiency
  • Qualcomm Protocol Controller Supports QC2.0 andQC3.0
  • Output 5 V/2.00 A, 9 V/1.67 A and 12 V/1.25 A
  • Highly Configurable Power and Current Limit Profiles
  • Standby Power < 75 mW @ 5 V Output
  • Support Output Capacitor Discharge Function whilePortable Device is Unplugged or during Transitionfrom Higher to Lower Output Voltage
  • Smooth Output Voltage Transition

Typical applications

  • Quick Charge 3.0, Cell Phone, Laptop Charger
