The recommended operating voltage range for the TL3414AIDR is 4.5V to 16V, although it can operate up to 18V with reduced performance.
To ensure stability, a minimum of 10nF capacitor should be connected between the COMP and FB pins, and the output voltage should be decoupled with a 10uF capacitor.
The maximum output current of the TL3414AIDR is 1.5A, but it can be increased to 3A with an external transistor.
The output voltage can be adjusted by changing the ratio of the resistors connected to the FB pin, or by using a potentiometer to adjust the voltage divider.
The TL3414AIDR is rated for operation up to 125°C, but its performance may degrade at high temperatures. It's recommended to derate the output current and voltage at high temperatures.
