Working Principle of ISL97645AIRZ-TK

The ISL97645AIRZ-TK operates in a voltage-limiting current regulation mode, using an on-chip adjustment pin to set the desired voltage level. It then uses a current sensing circuit to monitor the input current and determine when to charge or discharge its internal capacitors to maintain the correct output voltage. The internal sense resistor allows the IC to detect a wide range from small changes in current up to large changes. Once the output voltage reaches the set level, the IC switches into an ultra-low power mode, allowing it to achieve high efficiency when the load is low.

The IC also offers a variety of protection functions, including over-voltage and over-current protection, as well as short-circuit protection. In addition, the use of an external resistor can provide a current limit setting, allowing the IC to work with a wide range of input currents while maintaining a stable output voltage.
