ACT4529EVK1 User's Guide
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.
