Non-Synchronous Boost
Controller
The 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.
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.
