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, control°C duty cycle oscillator with an active current limit circuit, driver and high current output switch. This series is specifically designed for incorporating in Step-up, Step-Down and Voltage-Inverting applications with a minimum number of external components.
