A switch-mode 0–30 V / 3 A bench supply
Published in issue 400, April 2010
This power supply is based on an integrated switching regulator to keep the component count within reasonable limits. The functional units of this IC include voltage regulation, switching signal generation, and integrated power switch. This means that only a few external components are necessary. * Adjustable secondary-side switch-mode power supply (buck converter)
* Output voltage 0–30 V (typical) (25 V minimum)
* Adjustable current limiting up to 3 A
* Maximum output power 90 W
* Compact PCB layout
* Switching frequency 52 kHz
* Parts kit available from the Elektor Shop
