1.5 A 280 kHz/560 kHz

Boost Regulators

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.
