AL8811
Boost/Buck/Inverting DC-DC CONVERTER
Description
The AL8811 is a monolithic control circuit containing the primary
functions required for DC-to-DC converters. These devices consist of
an internal temperature compensated reference, comparator,
controlled duty cycle oscillator with an active current limit circuit, driver
and high current output switch. This series is specifically designed for
incorporating in Boost, Buck and voltage-inverting applications with a
minimum number of external components.
