ISL6422BERZ

Special Purpose Regulators Overview

The ISL6422BERZ is a dual-output LNB supply and control voltage regulator with an I2C interface, designed for advanced satellite set-top box applications. It operates from a 12 V input to provide regulated outputs of 13.3 V to 18.3 V and 14.3 V to 19.3 V at up to 750 mA. The device utilizes a boost topology with a 24 kHz switching frequency and 93% maximum duty cycle. It features open-drain output types, non-isolated architecture, and SMD/SMT installation in a QFN-EP-24 package. Operating temperatures range from -20°C to +85°C.
