#tl431

MOST RECENT

A switch-mode PSU hacked! I was planning to use this PSU for my #DIYsmartAutomaticDrinkDispenser project, but 12V DC is quite low for the #peltier #thermoelectric #cooler, and the adjustment on the #PSU didn't go beyond 13,7V (see graph - 5th image). So I partially reverse engineered the feedback circuitry and modified a resistor, that was part of the #TL431 comparator circuit, and now it goes up to around 17,2V - much more suitable voltage range for operating peltiers.
Overall, it was a successful day, the #SmokeTest was thankfully negative, and even no breakers were tripped while making this mod. Very happy with the outcome!

TL431 smd SOT23

TL431:programmable shunt regulator.the output voltage may be set to any value between VREF(approximately 2.5 volts) and 36 volts with two external resistors these devices have a typical dynamic output impedance of 0.2 ohm active output circuitry provides a very sharp turn_on characteristic,making these devices excellent lent replacement for zener diodes in many applications.
