I am doing a project using a peltier TEC1-12706, however I am stuck on powering up the device. I am using a computer adapter power supply(20V;90W) and I it coupled with a synchronous buck-boost module to bring it down to 12V. During the initial seconds the power supply did handle powering up the module but later smoke came out with my buck-boost converter.
- What are your recommendations for the powersupply? BTW, the peltier supply was also coupled with computer cooler which consumes around 500mA and a raspi fan on the other side.
- Follow-up question, is the peltier usually reads as short using DMM buzz test? Ohmmeter around 1ohm only. Sorry, this is my first time working with the component.
