AEK-POW-L5964V1, AUTODEVKIT, BUCK SWITCHING REGULATOR

Digitally controlled DC-DC converter with L5964 for automotive applications. This expansion board is designed for power car or truck body applications requiring different voltages such as USB-PD or infotainment. It has two independent converters that can deliver a fixed or variable output voltage via MCU control. The output current can be up to 3A per channel. The board includes monitoring circuitries 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. This expansion board is part of the AutoDevKit initiative A demo application and an AutoDevKit component plugin are also provided for the SPC5-STUDIO tool environment.
