Description
GM3255 products are 280 kHz switching regulators with a
high efficiency, 1.5 A integrated switch. These parts oper-
ate 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 reg-
ulation, as well as a practical means for limiting current.
Combining high frequency operation with a highly inte-
grated regulator circuit results in an extremely compact
power supply solution. The circuit design includes provi-
sions for features such as frequency synchronization, shut-
down, and feedback controls for either positive or negative
voltage regulation.
