Working Principle

The main working principle of the LTC3775IUD#TRPBF is that it uses an analog sensed input voltage and a digital control loop to determine the output voltage. When the input voltage drops below the set voltage, the output voltage of the LTC3775IUD#TRPBF will increase to maintain the pre-set voltage. It also uses a high-speed PWM control strategy to regulate the system, with a minimum load current of 0.1A to ensure it has the ability to maintain a constant voltage when the load is variable. The LTC3775IUD#TRPBF is also equipped with a current limit feature that prevents the output current from exceeding a desired setting. This feature is useful in order to protect the system from excessive current draw that can lead to system damage. The LTC3775IUD#TRPBF also features a cycle-by-cycle current limit, which ensures that the current level is limited during each cycle in order to protect the power components from damage and overheating.
