Infineon Technologies CYPAS111A0-24LQXQ | Demoboard 33W USB-PD PAG1P/S
USB PD power adapter secondary side controller
Overview
| Topology | Flyback Converter |
| Input voltage | 90-265 V |
| Switching frequency | 20-150 kHz |
| IC revision | 4.2 |
Description
Cypress CYPAP111 part of PAG1P family is designed for a secondary controlled AC/DC flyback converter topology. In this topology, the voltage and current regulation is performed by the secondary controller. CYPAP111 is responsible for providing the start-up function, driving the primary side FET as well as responding to fault conditionsCypress CYPAS111 part of PAG1S family is an integrated secondary-side synchronous flyback controller, synchronous rectifier (SR) controller, and charging port controller. CYPAS111 is designed to fit a secondary-controlled flyback system with a primary startup controller (CYPAP111) with secondary-side sensing and regulation. CYPAS111 is targeted towards mobile power adapters, it fits well into high-efficiency AC-DC flyback designs for USB Power Delivery, Qualcomm Quick Charge, and other standard charging protocols. CYPAS111 also supports USB Power Delivery (USB PD 3.0) Programmable Power Supply (PPS) mode.The interface between CYPAP111 and CYPAS111 is through a Pulse Edged Transformer and its associated circuitry.This document contains test results of PAG1P + PAG1S based 33W Power Adapter solution board. The tests were performed on this board which is equipped with Cypress CYPAP111A1-10SXQ on primary and CYPAS111A1-24LQXQ on secondary section of the converter
