onsemi DC DC Switching Controllers NCV887101D1R2G

The NCV887101D1R2G is an automotive-grade, adjustable output non-synchronous boost controller designed to drive an external N-channel MOSFET. It operates using peak current mode control with internal slope compensation and features an internal regulator for gate driver supply. The device supports a wide input voltage range from 3.2 V to 40 V DC, with a maximum load dump voltage of 45 V. Key protection features include undervoltage lockout, cycle-by-cycle current limiting, hiccup-mode short-circuit protection, and thermal shutdown. The controller also incorporates a soft-start mechanism and a low quiescent current sleep mode, making it suitable for power-sensitive applications. The switching frequency is externally synchronizable, allowing for flexibility in design. The NCV887101D1R2G is AEC-Q100 qualified, ensuring reliability in automotive applications, and is offered in a Pb-free SOIC-8 package.
