General Description

Intended for analog and digital satellite receivers, this dual low-noise block converter regulator (LNBR) is a monolithic linear and switching voltage regulator, specifically designed to provide the power and the interface signals to two LNB down converters via coaxial cables.

The A8286 requires few external components, with the boost switches and compensation circuitry integrated inside of the device.

A high switching frequency is chosen to minimize the size of the passive filtering components, further assisting in cost reduction.

Overview

A8286 Dual LNB Supply and Control Voltage Regulator.

Key Features

  • 2-wire serial I2C™ -compatible interface: control (write) and status (read).
  • LNB voltages (16 programmable levels) compatible with all common standards.
  • Tracking switch-mode power converter for lowest dissipation.
  • Integrated converter switches and current sensing.
  • Output current limit of 900 mA typical, with 48 ms timer.
  • Static current limit circuit allows full current at startup and 13→18 V output transition; reliably starts wide load range.
  • Push-pull output.
