TPS65235-1 Datasheet LNB Voltage Regulator

Manufacturer: Texas Instruments

Overview: TPS65235-1 SLVSDP1F – JANUARY 2017 – REVISED MAY 2023 TPS65235-1 LNB Voltage Regulator With I2C Interface.

General Description

Designed for analog and digital satellite receivers, the TPS65235-1 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 multi-switch box.

The device offers a complete solution with minimum component count, low power dissipation together with simple design and I2C standard interface.

Key Features

  • Complete integrated 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-mĪ© low Rds(on) internal power switch.
  • Boost switching frequency 1-MHz or 500-kHz selectable.
  • Audible noise avoided at forc.
