Infineon Technologies USB-C PAG1 Solutions

Infineon Technologies USB-C PAG1 Solutions is used for AC-DC power applications and features an integrated USB Power Delivery (PD) controller. This allows OEMs to build reliable, efficient, and cost-effective power adapters for USB-C chargers. PAG1 is offered as a two-chip solution with a primary start-up controller (PAG1P) and a single-chip secondary-side controller (PAG1S). It integrates a synchronous rectification driver, PD controller, 30V-tolerant regulator, high-voltage NFET gate drivers, OVP, SCP, and OCP protection. Infineon PAG1 is a secondary-side-controlled flyback solution with dynamically variable switching frequency for best-in-class efficiency and reliability.

Features

PAG1S FEATURES
- Works with both primary-side and secondary-side controlled flyback designs
- Integrates secondary-side regulation, synchronous rectifier (SR), and charging port controller
- Supports Quasi-Resonant (QR) or Critical Conduction Mode (CrCM), valley switching, Discontinuous Conduction Mode (DCM), and burst mode for light load operations
- Switching frequency range of 20kHZ to 150kHZ
- Higher efficiency across the line and load levels with independent CC/CV loop control
- Supports USB PD 3.0 with PPS (USB-IF certified, TID:1475), QC4+
- Supports legacy charging protocols: BC v1.2, AFC, and Apple charging
- Integrates low side current sense amplifier and V_BUS NFET gate drivers
- Available in a 24 QFN (4×4) package

PAG1P FEATURES
- Works across universal AC main input 85VAC to 265VAC
- Synchronizes to PWM from the secondary side using a pulse edge transformer
- Integrated low-side gate driver to drive primary side FET
- Integrated high-voltage start-up and shunt regulator
- Supports X-cap discharge mode for enhanced efficiency
- Integrated line UV, OCP, and secondary OVP
- Fixed auto-restart timer for fault recovery
- Programmable soft-start configurable with external capacitor
