1.5 A 280 kHz/560 kHz

Boost Regulators

The CS5171/2/3/4 products are 280 kHz/560 kHz switching

regulators with a high efficiency, 1.5 A integrated switch. These parts

operate over a wide input voltage range, from 2.7 V to 30 V. The

flexibility of the design allows the chips 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 either positive or negative voltage regulation. These parts are

pin−to−pin compatible with LT1372/1373.
