DCDC-IBB_-12V

High Voltage Inverting Buck-Boost Converter +48V to -12V 2A

Based on the LM5085 from Texas Instruments

  • Input: +45V to +63V DC (nominal +48V)
  • Output: -12V DC (variable)
  • Max. Output Current: 2A (max. 2.2A)
  • Disable Jumper
  • Output-On LED

Voltage configuration

To set the voltage, turn the Trim-Potentiometer until you've reached your desired Output.

NOTE: Don't set Voltages below -16V, because it could damage your circuit! (If you don't replace certain Capacitors)
