STMicroelectronics ST STEVAL-L3751V12 DC-DC Converter for DC-DC Buck Converter for L3751

The STMicroelectronics DC-DC buck converter based on the L3751 controller is a synchronous buck evaluation board that features an extreme voltage conversion ratio over switching frequency. The board provides a regulated 5 V output at 230 kHz switching frequency. The output voltage can be easily set to 12 V using a jumper connector. Different voltage output can be selected by changing a resistor to a lower VIN range.
