CYPAP212 Overview
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...
CYPAP212 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-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
