AL8811

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.
