CYPAP212 - PAG2P primary-side startup controller

Download the CYPAP212 datasheet PDF. This datasheet also covers the CYPAP211 variant, as both devices belong to the same pag2p primary-side startup controller family and are provided as variant models within a single manufacturer datasheet.

General Description

EZ-PD™ PAG2P (Power Adapter Generation 2 Primary) is Infineon’s second generation integrated primary-side startup controller for AC/DC applications targeting the mobile power adapter segment.

Key Features

  • Works across universal AC mains input from 85 VAC to 265 VAC.
  • Low-side gate driver to drive primary side FET.
  • A logic-level gate driver to control external high-side floating gate driver IC (ACF).
  • Free-running oscillator with PWM generator for start-up.
  • Line under voltage protection (UVP) and line overvoltage protection (OVP).
  • Secondary overvoltage protection via auxiliary winding (SOVP).
  • Overcurrent protection (OCP).
  • Short.

CYPAP211/ CYPAP212 EZ-PD™ PAG2P primary-side startup controller General description EZ-PD™ PAG2P (Power Adapter Generation 2 Primary) is Infineon’s second generation integrated primary-side startup controller for AC/DC applications targeting the mobile power adapter segment. EZ-PD™ PAG2P interface’s with the AC mains rectified output on the primary side and receives the necessary PWM signal from the secondary side to provide a regulated output voltage. EZ-PD™ PAG2P is designed to operate in two configurations: half-bridge running in non-complementary state (Active Clamp Flyback) or a low-side switch configuration with a snubber circuit (QR, DCM, CCM).
