Working Principle

The TL2575HV-ADJIKV works by using a Linear Regulated Voltage (LRV) topology. This is a type of pulse-width modulation (PWM) control that offers high efficiency when compared to traditional linear regulator techniques. The converter utilizes a synchronous buck topology, using an internal MOSFET switch to convert the input voltage to a regulated voltage. This is done by switching the MOSFET at the frequency of the Control Loop.

The swing of the Control Loop modulates the on-time of the MOSFET, resulting in a smoothly regulated output voltage. When the load current changes, the Control Loop will adjust itself to maintain a constant output voltage. The TL2575HV-ADJIKV also features a soft start circuit for smooth power supply ramping and voltage overshoot protection. Additionally, it has an output over-current protection, output short circuit protection, and an on/off enable control.
