NCV8853
Automotive Grade
Non-Synchronous Buck
Controller
The NCV8853 is an adjustableâoutput nonâsynchronous buck
controller which drives an external Pâchannel 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 softâstart, undervoltage lockout,
cycleâbyâcycle current limit, hiccupâmode overcurrent protection,
hiccupâmode shortâcircuit protection.
Additional features include: power good signal, low quiescent
current sleep mode and externally synchronizable switching
frequency.
