EZ-PD™ PAG1P

Primary side startup controller

General description

EZ-PD™ PAG1P (Power Adapter Generation 1 Primary) is 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. EZ-PD™ PAG1P is available in a 10-pin

SOIC package.

EZ-PD™ 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.

Features

• Works across universal AC mains input 85 VAC to 265 VAC

• 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

• Supports X-cap discharge mode to obtain better efficiency

• Integrated high-voltage start-up and shunt regulator

• Synchronizes to PWM from secondary side using a pulse edge Transformer
