The ADP3836EGN#TRPBF part of Analog Devices is a synchronous step-down voltage regulator designed to provide a regulated DC output from an input voltage of up to 38 V. This device uses a fixed frequency, current-mode PWM control, making it suitable for high step-down ratios with low component count and efficiency. It includes an internal soft-start, short-circuit protection, thermal shutdown, and cycle-by-cycle current limit, allowing for a safe and robust operation. Additionally, the adjustable over-voltage and over-current protection features provide excellent protection from input and output surges and inrush currents. This versatile IC is suitable for powering a wide range of systems such as portable electronics, industrial equipment, and custom applications.
