NCV8853 شرح
NCV8853
Automotive Grade
Non-Synchronous Buck
Controller
The NCV8853 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: power good signal, low quiescent
current sleep mode and externally synchronizable switching
frequency.
