Overview

GBI1430 is a 40V, 3.5A step-down converter with an integrated 80mΩ high-side MOSFET. The device features a wide input voltage range of 4.0V to 40V, suitable for various applications powered by unregulated supplies, such as industrial or automotive applications. It operates in peak current mode and supports a wide adjustable switching frequency set by an external resistor. The quiescent current in sleep mode is 100uA, and the shutdown current is 1uA, making it well-suited for battery-powered systems. The device integrates multiple protection features, including cycle-by-cycle current limiting, thermal shutdown, output overvoltage protection, and input undervoltage lockout. It is available in an 8-pin eSOP-8L package.
