Intended for analog and digital satellite receivers, the LNB (low noise block) converter regulator is a monolithic linear and switching voltage regulator, specifically designed to provide power and interface signals to an LNB downconverter, via coaxial cable.
The device uses a 2-wire bidirectional serial interface, compatible with the I2C (Inter-C bus) standard, that operates up to 400 kHz.
The A8285 is supplied in a 16-lead plastic power SOIC with internally fused leads for thermal dissipation. The A8287 is supplied in a 24-lead plastic power SOIC with internally fused leads. Both devices are also available in lead (Pb) free versions, with 100% matte tine leadframe plating.
