HY5171 is a 280kHz switching regulators with a high efficiency, 1.5A integrated switch. These parts operate over a wide input voltage range, from 2.7V to 30V. The flexibility of the design allows the chips to operate in most power supply configurations, including boost, flyback, inverting, and SEPIC. HY5171 utilize current mode architecture, which allows excellent load and line regulation, as well as a practical means for limiting current. The circuit design includes provisions for features such as frequency synchronization, shutdown, and feedback controls for either positive or negative voltage regulation.
