CS5173EDR8G DC-DC Power Conversion by ON Semiconductor

Boost Regulator, Positive, 1.5 A, 560 kHz


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 of the Boost Regulator 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.
