Image of STMicroelectronics' AEK-POW-L5964V1 Expansion Board STMicro’s AEK-POW-L5964V1 expansion board is designed for power car or truck body applications requiring different voltages, such as USB-PD or infotainment. The expansion board has two independent converters that can deliver a fixed or variable output voltage via MCU control. The output current can be up to 3 A per channel.

The board monitors circuitry for input and output voltages and LEDs to indicate operating status. EMI is minimized through appropriate filtering techniques. The converters are based on the L5964 step-down switching regulators (in buck topology) with overcurrent and overtemperature protection. The L5964 integrates the control, power switches, and monitoring circuitries of both converters alongside features such as watchdog, wake-up, and reset.

The AEK-POW-L5964V1 expansion board is part of the AutoDevKit initiative. It can be plugged on top of additional boards via a 4x20 male/female connector, which is compatible with the 4x37 MCU male connector on SPC58EC-DISP or AEK-MCU-C4MLIT1 evaluation boards. A demo application and an AutoDevKit component plugin are also provided for the SPC5-STUDIO tool environment.
