A8287 - LNB Supply and Control Voltage Regulator

This page provides the datasheet information for the A8287, a member of the A8285 LNB Supply and Control Voltage Regulator family.

Description

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.

Features

  • LNB selection and standby function.
  • Provides up to 500 mA load current.
  • Two-wire serial I2C interface.
  • Built-in tone oscillator, factory-trimmed to 22 kHz; facilitates DiSEqC™ 2.0 encoding.
  • Auxiliary modulation input.
  • 22 kHz tone detector facilitates DiSEqC™ decoding (A8287 only).
  • Tracking switch-mode power converter for lowest dissipation.
  • LNB overcurrent protection and diagnostics.
  • Internal overtemperature protec.
