AEK-POW-L5964V1 Data brief Digitally controlled DC-DC converter with L5964 for automotive applications Features Dual channel, independent, step-down regulators with integrated synchronous MOSFETs Output current up to 3 A each channel Channels can be paralleled to obtain a higher current supply Input voltage range from 6 to 14 V Digitally selectable fixed output voltages: 3.3 - 5 - 9 V PWM programmable output voltages with 20 mV steps over a range of 3.3 - 11 V Outputs protected against short-circuit and overcurrent Input and output voltage monitors (UV or OV) and power good signals Thermal protection thanks to the integrated thermal sensor Additional 3.3 V output by internal linear regulator Watchdog, reset, in/out synchronisation for available converters Board size: 84.7 mm x 81.3 mm Maximum component height: 10 mm Automotive grade qualified ST components Included in the AutoDevKit initiative RoHS and China RoHS compliant WEEE compliant Product summary Applications digitally controlled DC- USB-PD 2.0 and 3.0 supplies DC converter with AEK-POW- Car infotainment supply L5964 for automotive L5964V1 In-car DC-DC modules and supply applications monolithic dual 3.5 A step-down switching L5964 Description regulator with LDO The AEK-POW-L5964V1 expansion board is designed for power car or truck body AutoDevKit library STSW- applications requiring different voltages, such as USB-PD or infotainment. It has two plugin for SPC5- AUTODEVKIT independent converters that can deliver a fixed or variable output voltage via MCU STUDIO control. The output current can be up to 3 A per channel. code generator, quick The board includes monitoring circuitries for input and output voltages, and LEDs to resource configurator and Eclipse indicate operating status. EMI is minimized through appropriate filtering techniques. SPC5-STUDIO development The converters are based on the L5964 step-down switching regulators (in buck environment for SPC5 topology) with overcurrent and overtemperature protection. The L5964 integrates the MCUs control, power switches and monitoring circuitries of both converters alongside MCU discovery board features such as watchdog, wake-up and reset. for SPC5 Chorus 4M AEK-MCU- automotive The AEK-POW-L5964V1 expansion board is part of the AutoDevKit initiative. It can C4MLIT1 microcontroller with be plugged on top of additional boards via a 4x20 male/female connector, which is CAN transceivers 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.
