1.5 A 260 KHz Boost Regulator

The NCV5171 is a 280 kHz Switching Regulator with a high efficiency, 1.5 A integrated Switch The part operates over a wide input voltage range, from 2.7 V to 30 V. The flexibility of the design allows the chip to operate in most power supply configurations, including boost, flyback, forward, inverting, and SEPIC. The IC utilizes current mode architecture, which allows excellent load and line regulation, as well as a practical means for limiting current. Combining high frequency operation with a highly integrated Regulator circuit results in an extremely compact power supply solution. The circuit design includes provisions for features such as frequency synchronization, shutdown, and feedback controls for positive voltage regulation. This part is pin-to-pin compatible with LT1372 1373 and is the automotive version of the CS5171.
