Cypressопорное решение

The CCG3PA 27W Mobile Power Adapter Board is a receptacle based Type-C power adapter which supports a maximum power profile of 27W (9V, 3A). The two major components on the board are Cypress’s EZ-PD CCG3PA (CYPD3175-24LQXQ) controller and Power Integrations InnoSwitch family’s AC-DC controller. This design is targeted towards mobile phone Power Adapters.

CCG3PA regulates the VBUS voltage by controlling the feedback node of the InnoSwtich AC-DC controller. CCG3PA monitors and handles fault protection like Over-Voltage, Under-Voltage, Over-Current, Short-Circuit and Over-Temperature. CCG3PA drives the external PFET and also controls VBUS discharge with integrated discharge resistors. CYPD3175-24LQXQ is factory programmed with DFP CC with Direct Feedback Bootloader, the application firmware for this solution is available in CCGx Power SDK 3.1.0 and any further customization can be done using the EZ-PD™ Configuration utility.

The EZ-PD™ CCG3PA Evaluation Kit (CY4532) is available at Digi-Key along with CCG3PA silicon. CY4532 can be used as a vehicle for CCG3PA-based USB Type-C Power Adapter (PA), USB Type-C mobile charger and USB Type-C Power Bank (PB) applications. The below reference design is available with full hardware design files (schematic, layout, etc.) and firmware for customers to reduce design cycle.

Reference Design Features:

  • Delivers up to 27W of power to charge USB PD3.0/QC 4.0 enabled mobile phones

  • Supports USB Power Delivery 3.0 for Programmable Power Supply (PPS)

  • Supports Qualcomm Quick Charge (QC) 4.0• Integrates VBUS-to-CC short protection

  • Reduces BOM with integrated:

  1. Single-chip primary and secondary side controllero 30-V Tolerant regulator

  2. VBUS PFET gate drivers

  3. Feedback amplifier to directly drive InnoSwitcho Low-side current sense amplifier

  4. Legacy charge support on DP/DM lineso ESD on VBUS, CC and DP/DM
