NCV890200PDR2G

The NCV890200PDR2G from ON Semiconductor is a fixed-frequency, monolithic buck switching regulator designed for automotive battery-connected applications. It supports input voltages from 4.5 V up to 36 V and can withstand load dump conditions up to 40 V. This regulator is suitable for systems requiring low noise and a small form factor, commonly found in automotive driver information systems.

Key electrical specifications include an output current capability of 2 A, a switching frequency of 2 MHz, and an adjustable output voltage down to 0.8 V with a tolerance of ±1.75%. It features an internal N-channel power switch, a 1.4 ms internal soft-start, and a cycle-by-cycle peak current limit of 2.2 A. Protection features such as short circuit protection enhanced by frequency foldback and thermal shutdown are integrated.

The device is available in an 8-SOIC-EP package with surface mount mounting type. Its operating temperature range is -40°C to 150°C (TJ). The NCV prefix indicates suitability for automotive and other applications requiring unique site and control change requirements, with AEC-Q100 qualification and PPAP capability. It is also Pb-Free and RoHS Compliant.

Applications for the NCV890200 include audio systems, infotainment, safety vision systems, and instrumentation.
