9v Stepup Voltage Regulator Overtemperature Shutoff

Hello,

For your 9v Stepup Voltage Reg (Pololu 9V Step-Up Voltage Regulator U3V12F9) what is temperature at which the the overtemp shutoff kicks in? Also do you have any data on efficiency as a function of ambient temperature (at say 6v for VIN)?

Thanks,
Kevin

Hi, Kevin.

The overtemperature protection typically activates around 155°C. Unfortunately, we have not characterized the affect of ambient temperature on the regulator’s efficiency. The efficiency graphs shown on the regulator’s product page were obtained at room temperatures. What temperature range do you want to use the U3V12F9 regulator in?
