Product Overview

CYPAP111A3-10SXQT is a EZ-PD™ PAG1P (power adapter generation 1 primary) Infineon’s primary-side start-up controller for AC/DC applications targeting the mobile power adapter segment. EZ-PD™ PAG1P interfaces directly with either the AC mains in an X-cap discharge mode or the DC output of a bridge rectifier. EZPD™ PAG1P is designed for a secondary controlled AC/DC flyback converter topology. In this topology, voltage and current regulation is performed by the secondary controller. EZ-PD™ PAG1P is responsible for providing the start-up function, driving the primary side FET as well as responding to fault conditions.
  • Works across universal AC mains input 85VAC to 265VAC
  • Low-side gate driver to drive primary side FET
  • Line undervoltage protection (UVP) and line overvoltage protection
  • Overcurrent protection (OCP), overvoltage protection (OVP) during soft-start
  • Programmable soft-start configurable with external capacitor
  • Fixed auto-restart timer for fault recovery, integrated high-voltage start-up and shunt regulator
  • Supports X-cap discharge mode to obtain better efficiency
  • Synchronizes to PWM from secondary side using a pulse edge transformer
  • 10-pin SOIC package
  • Extended industrial temperature range from -40°C to +105°C
