Working Principle

The LT8610ABIMSE#PBF is a synchronous step-down DC-to-DC switching regulator. The device converts an input voltage to a regulated output voltage using a buck switching topology. This topology requires an external switch MOSFET which switches at a given frequency. The PWM control and frequency is determined by an internal oscillator. The topology is capable of providing constant-voltage and constant-current regulation. The output voltage is regulated using a feedback-control loop, with an internal error amplifier. The error amplifier compares the feedback voltage against a fixed reference voltage and adjusts the duty cycle of the switch MOSFET accordingly. The output current is regulated by switching off the MOSFET when the output current reaches the programmed limit. The device is protected against inrush current and over-temperature.
