NCV97200
Description
The NCV97200 is a 2- output monolithic regulator consisting of
1 buck regulator and 1 boost regulator with supervisory functions including window voltage monitoring on all outputs and a window watchdog. This product is ideal for ADAS (Advanced Driver Assistance Systems) applications and utilizes an independent voltage reference and an adjustable independent oscillator to realize the supervisory features
.
A 40 V non- synchronous buck regulator converts the battery supply voltage to a 3.3 V output, and delivers up to 3 A (peak). This output rail may be used as the low voltage input voltage for the non- synchronous secondary boost converter. The secondary boost is fixed and is intended to supply a low current 5.0 V rail for In- Vehicle Networking circuits (IVN).
All internal MOSFETs are N- channel devices, and a bootstrap circuit is used to drive the buck high- side MOSFET. Both SMPS outputs use peak current mode control with internal slope pensation. The IC incorporates an...
