EZ-PD™ PAG1: Power Adapter Generation 1

概要

Integrated QR flyback chipset for USB-PD adapters and chargers

EZ-PD™ PAG1 is a complete AC-DC charger and adapter solution with integrated USB PD. It is a 2-chip solution with EZ-PD™ PAG1P and EZ-PD™ PAG1S and works in a secondary side controlled Quasi-resonant (QR) Flyback topology.

EZ-PD™ PAG1P is a primary start-up controller for AC-DC applications. It is designed to work with EZ-PD™ PAG1S in a secondary side-controlled AC-DC flyback converter topology where the voltage and current regulation is performed by EZ-PD™ PAG1S, and EZ-PD™ PAG1P provides the start-up function, drives the primary FET, and responds to the fault condition. The EZ-PD™ PAG1P also supports X-cap discharge-mode for better efficiency.

EZ-PD™ PAG1S is a single-chip, secondary-side controller that integrates the synchronous rectification driver, PD controller, and a wide range of protection circuits. The controller
is designed to support a traditional primary controlled flyback architecture, as well as a more efficient secondary controlled flyback architecture with a simple primary startup controller. EZ-PD™ PAG1S helps design world-class, high-performance power adapters at lower BOM costs.

 

EZ-PD™ PAG1P

  • Works across universal AC main input 85 VAC to 265 VAC
  • Synchronizes to PWM from the secondary side using a pulse edge transformer
  • Integrated low-side gate driver to drive primary side FET
  • Integrated high-voltage start-up and shunt regulator
  • Supports X-cap discharge mode for enhanced efficiency
  • Integrated line UV, OCP, and secondary OVP
  • Fixed auto-restart timer for fault recovery
  • Programmable soft-start configurable with an external capacitor

EZ-PD™ PAG1S

  • Works with both primary-side and secondary-side controlled flyback designs
  • Integrates secondary-side regulation, synchronous rectifier (SR), and charging port controller
  • Supports quasi-resonant (QR) or critical conduction mode (CrCM), valley switching, discontinuous conduction mode (DCM), and burst mode for light load operations
  • Switching frequency range of 20 kHz to 150 kHz
  • Higher efficiency across the line and load levels with independent CC/CV loop control
  • Supports USB PD 3.0 with PPS (USB-IF certified, TID:1475), QC4+ Supports legacy charging protocols: BCv1.2, AFC, and Apple charging
  • Integrates low-side current sense amplifier and VBUS NFET gate drivers
  • Available in a 24 QFN (4x4) package
  • Highly integrated 2-chip power adapter solution including SR+PD controller, all necessary protection circuitry, and FET drivers to drive the primary, SR, and load FETs
  • Flexibility to program the device according to the customer’s needs, to configure the parameters across multiple platforms as well as to upgrade the firmware on the field
  • Reduced BOM
