Description

The GM3255 products are 280 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 GM3255 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 of GM3255 includes provisions for features such as frequency synchronization, shutdown, and feedback controls for either positive or negative voltage regulation.
