By ON Semiconductor 108
ON Semiconductor's NCV8873 is an adjustable output, non-synchronous boost controller which drives an external N-channel MOSFET. The device uses peak current mode control with internal slope compensation. The IC incorporates an internal regulator that supplies charge to the gate driver. Protection features include internally set soft-start, undervoltage lockout, cycle-by-cycle current limiting, and thermal shutdown. Additional features include low quiescent current sleep mode and externally synchronizable switching frequency.
