link to page 20 Boost Regulators, 1.5 A, 280 kHz/560 kHz CS5171, CS5172, CS5173, CS5174 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, 8 and SEPIC. The ICs utilize current mode architecture, which allows 1 excellent load and line regulation, as well as a practical means for
SOIC−8
limiting current. Combining high frequency operation with a highly

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
