I want to build an electronic circuit to convert an NTC 10 kiloohm (B=3950) signal into an output voltage that can supply 2-3 amps. The output voltage should correspond to the measured temperature (4V at 25°C to 12V at 50°C), i.e. have a range of 4V to 12V DC. Is this typically done with a buck/boost converter and a coil and capacitor? Or is there a ready-made chip that I can use to achieve a maximum output voltage of 12V DC? The power supply comes from a PC power supply (12V DC). The purpose of the circuit is to control the speed of one or more DC fans using a changing operating voltage at the fan, without using PWM. To linearize the NTC and process the voltage, I was thinking of using a TLV9002 from TI. Can anyone help me with the rest of the circuit? No programming, no software, no Arduino, no PLSOC, just more or less classical built up with only a few compenents. Is that possible?

Hi everybody, I´ve got a seven-segment-display, 3 digit, height is 0,28 inch. The item number printed on is i.e. 2381BG-2-6. This mudule has six (6) pins on the bottom side only. I can´t find any maker or distributor to get datasheet from to prepare the programming with which µ-controller etc. Only those more or less classic manufacturers with 8 pins per digit. Can someone help me here? Like to prepare a temperature display for our parts. Many thanks in advance!!!
