HT7463 wide voltage DCDC step-down module

This module is based on HT7463A and can be used as a verification board.

Applications designed using this chip: 12-24V power supply is used in competitions. The power of the whole machine is relatively large. There will be a peak voltage exceeding the standard voltage at the moment of switching. This chip can safely complete the expected functions after actual testing.

Up to 52V input, as low as 1V output, up to 600ma step-down module, suitable for independent DCDC power supply for control boards using 12V/24V/48V driven robots or industrial equipment. 600ma is sufficient for microcontrollers and peripheral circuits.

The difference between HT7463A/B is that the frequency is different but other parameters are the same. For details, please refer to the reference manual.

This module is directly welded to the main control board during the competition (for ease of maintenance). The half-hole process is the best, but the half-hole process is too expensive, so we compromised and placed a large through hole on the edge of the module. After processing Grind the edge of the pad to make a large half hole (actually measured, it can be soldered directly to the board without grinding). If you don't want to solder it directly, you can also solder the header pins and use the pad. It is compatible.

ps. I thought that to participate in the solicitation order, I would first draw a project and then open source it... I didn't expect that I would first create the project on the solicitation order interface... So after I finished the drawing, I created another project on the solicitation order interface to use the newly drawn project. After copying, the schematic and PCB preview thumbnails cannot be displayed on the homepage, which is very strange.

Physical picture of the module that has been welded to the control board: (As shown in the picture, if you do not need to control the output of the module, just connect EN and VIN directly)

The power supply to the microcontroller is normal

Test 12V input

Output 5v is normal

I don’t have a higher voltage power supply on hand. In the past, the 24V power supply continued to run normally during the robot competition.

In the actual competition, the shell was printed and made into a module.
