Beschreibung

This document describes the characteristics and operation of the active-semi ACT5101-101-REF01 reference design. This design features a 39W car charger reference design with a 27W USB-C output and a 12W USB-A output. The document provides setup and operation instructions, schematic, layout, BOM, and test data. This Reference Design demonstrates the ACT5101QI101 power management IC plus Cypress CYPD1275-24LQXQT USB PD3.0controller.This reference design is a good starting point for designs requiring slight variations from the base design. The base design is suitable as-is for many different power profiles. The “Certifications” paragraph in this User’s Guide shows the design’s existing certifications. Many derivative requirements are easily achievable with only firmware modifications to the Cypress controller. This design has been certified for 45W on the USB-C output.This design is a joint design with active-semi and Cypress. Cypress provides additional documentation on their website here: http://www.cypress.com/documentation/reference-designs/ez-pd-ccg3pa-usb-c-pps-39wdual-port-car-charger-power-adapter。This Reference Design features a 2-output car charger application. Three major components in the design are active-semi’s ACT5101 Integrated Buck-Boost Converter, active-semi’s ACT4527 Integrated Buck Converter, and Cypress’ CCG3PA (CYPD3175-24LQXQ) USB PD controller. The CCG3PA communicates with the downstream device to negotiate required power levels. It then communicates with the ACT5101 and ACT4527 to program them to meet the required power levels.- Input Voltage = 4V to 22V- USB-C Output up to 45W- USB-A Output up to 27W
