65V Input -12Vdc Output 1A synchronous buck DC/DC converter using LM5164

This is a step-down DC-DC converter mainly designed for applications such as high-cell-count battery packs, power tools, garden tools, and electric scooters, drones. Some of the features of the project is precision enable, input voltage UVLO, internal soft-start etc. The project operates over a wide input voltage range of 15V to 65V to provide a regulated 12V-1A output at 300Khz working frequency. D1 is the power LED, and 4 Pin male header connectors provided for input and output. The full-load efficiency of the project is 90% @ nominal input voltage of 48 V and an output voltage of 12 V. The switching frequency is set by resistor R4 at 300 kHz. The output voltage soft-start time is 3 msec.

i would like to build one of these using EasyEDA preferably to output 7.5v to 8v rather than 12v and power from 7 Nissan leaf modules that output about 55v nominal

i don’t see any schematic or board or well anything about the board i can see in the photo above on this page?

am i missing something here?
