Topic: Power supply 12-30V to 5V (Read 1 time) previous topic - next topic


Hi I need a power supply for my relay and solenoid driver board. Input voltage range is 12-30V and output voltage is +5V (1,5A max). Can I use this circuit for my needs?

Thanks Koudy

Looks reasonable. Have you tried to simulate it using National's WebBench simulator?

The Gadget Shield: accelerometer, RGB LED, IR transmit/receive, speaker, microphone, light sensor, potentiometer, pushbuttons


The concept is good. Here is a commerical example based on a LM2596 chip that I bought and it works great, plus it's adjustable via a pot control.
