onsemi NCV5173EDR2G

The NCV5171/73 products are 280 kHz/560 kHz switching regulators with a high efficiency, 1.5 A integrated switch. The parts operate 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 ICs utilize 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. These parts are pin−to−pin compatible with LT1372/1373.
