USB Type C Car Charger Solution

Description

This document describes the characteristic and operation of the Active Semi ACT4529EVK1 evaluation kit

(EVK). It provides setup and operation instructions, schematic, layout, BOM, and test data.

This EVK

demonstrates the ACT4529YH-T1011. Other ACT4529YH-Txxx options can be evaluated on this EVK by

replacing the IC and any other necessary components.

Features

The EVK is a complete, stand-alone USB-PD and QC2.0 car charger solution. It is built with an automotive car

charger form factor to show performance in a real form factor application. The EVK contains the high efficiency

ACT4925 step-down DC/DC converter that operates in either CV(Constant

Output Voltage) mode or

CC(Constant Output Voltage) mode.

The EVK features a USB Type C output connector with USB-PD, QC2.0, and USB Auto Detect decoding

protocols. Decoding is implemented with an on-board FUSB302TMPX USB Type-C controller and

STM32F030F4P6 MCU. The EVK provides up to 3.0A output current at 125kHZ switching frequency. It operates

from Vin=12V to 36V and provides an output voltage of 5.1V, 9.1V, or 12.1V depending on the load's requested

voltage. It charges Samsung and BC1.2 charging protocols at full charge current. Gerber files are available to

minimize time-to-market for applications that want to use the EVK as an end product.
