TPS65235 - LNB Voltage Regulator

General Description

Designed for analog and digital satellite receivers, the TPS65235 is a monolithic voltage regulator with I2C interface; specifically to provide the 13-V to 18-V power supply and the 22-kHz tone signal to the LNB down converter in the antenna dish or to the multiswitch box.

Key Features

  • 1 Complete Integrate Solution for LNB and I2C Interface.
  • DiSEqC 2.x, and DiSEqC 1.x Compatible.
  • Supports 5-V, 12-V and 15-V Power Rail.
  • Up to 1000 mA Accurate Output Current Limit Adjustable by External Resistor.
  • Boost Switch Peak Current Limit Proportional to LDO Current Limit.
  • Boost Converter with 140-mΩ Low Rds(on) Internal Power Switch.
  • Boost Switching Frequency 1-MHz or 500-kHz Selectable.
  • Dedicated Enable Pin for Non-I.
