1.5A 280kHz BOOST REGULATORS
DESCRIPTION
The AMC3202 is a 280kHz switching regulator with a
high efficiency, 1.5A integrated switch. The part operates over
a wide input voltage range, from 2.7V to 30V. The AMC3202
utilizes 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.
Build-in thermal protection to prevent the chip over heat
damage.
