Building a DC to DC voltage regulator

[dancingbear]

Could anybody please assist me.

I need to regulate 12 volts dc from a car battery down to 1.24 volts dc yet I still need to be able to draw 12 - 15 amps. Ideally I would like to be able to adjust the voltage. Does anybody have any ideas how I will be able to achieve this & if so, what components will I need?

Thanks

Here's a 20A buck regulator chip and application info from National Semiconductor:

for reaching out for assistance with building a DC to DC voltage regulator. This is a common task in the field of electronics and there are several ways to achieve this goal. One approach is to use a buck converter, which is a type of switching power supply that can efficiently step down voltage while maintaining a high current output. You will need to select a buck converter that can handle the desired input and output voltage and current levels. Additionally, you may want to consider using a variable resistor or potentiometer to adjust the output voltage. Other components that may be needed include capacitors, inductors, and diodes.

It is important to carefully select and test all components to ensure they can handle the desired voltage and current levels and operate within their specified parameters. It may also be helpful to consult with a knowledgeable colleague or reference materials for guidance on specific component selection and circuit design.

Overall, building a DC to DC voltage regulator can be a challenging but rewarding project. With careful planning and proper component selection, you should be able to achieve your desired output voltage and current levels. Best of luck with your project!
