CYPAP111A3-10SXQ

CYPAP111A3-10SXQ 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
