NCV8852_15 Datasheet, PDF (1/13 Pages) ON Semiconductor – Automotive Grade Non-Synchronous Buck Controller

NCV8852
Automotive Grade
Non-Synchronous Buck
Controller
The NCV8852 is an adjustable−output non−synchronous buck
controller which drives an external P−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 internal soft−start, undervoltage lockout,
cycle−by−cycle current limit, hiccup−mode overcurrent protection,
hiccup−mode short−circuit protection.
Additional features include: programmable switching frequency,
low quiescent current sleep mode and externally synchronizable
switching frequency.
