The board allows setting the output current from a min. of 0.05 A to a max. of 5 A for the entire output voltage range in 50 mA steps. It features several protection systems, such as short-circuit, overcurrent and thermal protection. The AutoDevKit software library includes dedicated components able to configure and drive the board via ST microcontrollers.

AEK-POW-100W4V1 functional block diagram DB4344 - Rev 2 page 2/7 AEK-POW-100W4V1 Hardware setup for USB-PD system level usage with AEKD-USBTYPEC1 kit 2 Hardware setup for USB-PD system level usage with AEKDUSBTYPEC1 kit You can set the required voltage and current level for the available buck channel by using simple primitives in the microcontroller. Moreover, if the system is complemented with a current sense device, the software performs system control in closed loop (otherwise only open current loop control is possible). The solution implementation is based on a microcontroller board plus a DC-DC power board, featuring Programmable Power Source (PPS) capabilities. To build a complete USB-PD system, the following system components are required: • an AEK-MCU-C4MLIT1 microcontroller board • an AEK-USB-2TYPEC1 USB Type-C dual-port interface board • USB power delivery protocol stack running on the microcontroller available in the AutoDevKit 2.1 Constant current mode The AEK-POW-100W4V1 embeds the circuitry to support constant current operation mode in both converters. In this operating mode, the converter stops maintaining constant output voltage like a voltage generator to start limiting the output current like a current source. This functionality is required to limit the output power in case of failures, as well as to charge the battery charging or connect a load behaving as a voltage source, as in the USB-PD 3.0 load direct charging operation. The circuit is based on an additional error amplifier in which the output pin is OR-ed with the voltage loop error amplifier output pin (COMP). Voltage and current loops regulate the output voltage or current according to the load resistance value. The error amplifier inverting input is connected to the current sensing circuit. The current sensing circuitry is not present on the AEK-POW-100W4V1 power board as it is implemented on the AEK-USB-2TYPEC1 dual-port USB Type-C expansion board: signals can be routed to the power board via the 4x20 pin connector J8 (I_SENSE_x).

To use the AEK-USB-2TYPEC1 for current sensing on the AEK-POW-100W4V1 board, decrease the gain of the current sensing signal amplifier (U801) from 100 to 50 by unsoldering the resistor from position R803 to solder it in position R804. The AEK-USB-2TYPEC1 hosts two USB Type-C port interfaces, but only one (CN701) can be used with the AEK-POW-100W4V1 power board, thus the second one (CN401) has to be disabled by removing R304 resistor.
