CYPAP211 Datasheet | Infineon

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-plementary state (Active Clamp Flyback) or a low-side switch configuration with a snubber circuit (QR, DCM, CCM). EZ-PD™ PAG2P is available in two versions: - Non X-cap applications - X-cap applications EZ-PD™ PAG2P is designed to plement a secondary controlled AC/DC flyback converter topology. In this topology, voltage and current regulation is performed by the secondary controller (EZ-PD™ PAG2S). EZ-PD™ PAG2P 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 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-circuit protection (SCP) - VCC pin short protection (VCCPSP) - Integrated VCC boost switch to support varied output voltage without the need for an external regulated LDO - Integrated high-voltage start-up and shunt regulator - A novel dual-output PET receiver is used to drive both high/low side switch using a single PET Datasheet .infineon.
