VP-PSDC-05-033 Project Power Supply

Posted by Vytas Sinkevicius on

Every embedded project needs to have power, usually 5 VDC and/or 3.3VDC. A switcher power supply provides high efficiency (= low heat) and a linear provides great regulation while smoothing out the high transients. The VP-PSDC-05-033 power supply has both and is designed for prototypes.
Schematic
The heart of the design is the LM2594-ADJ Switching Regulator. This provides a wide input voltage of up to 40 VDC, making it ideal for wall adapter power supplies in the 9, 12, 15 and 24 VDC range.
The complete data specs can be found here: LM2594
The linear regulator the is the MCP1825S-3302 from Microchip.

Specifications:

  • Model: VP-PSDC-05-033
  • Power Input: 9-24VDC
  • Power Output 1: 5.0VDC (Switching 150 kHz.)
  • Power Output 2: 3.3VDC (Linear)
  • Output Current: Up to 500 mA Combined 5VDC and 3.3 VDC
