Programmable Power Supply

Harun Tetik

Hello,

I am using a photodiode in my application. I want the bias voltage to be programmable. Bias voltage could be 0 to -10 volts. I want to control this voltage with digital interface(SPI,I2C etc.). How can i handle this? Is there any programmable power management ic?

Best regards

Hello Harun,

I don't think we have a power management IC like this, but you could use a microcontroller and DAC to control the voltage. See the link below for a list of our MSP430 microcontrollers which include a DAC.
