LNBH30:LNB supply and control IC with step-up and I²C interface

Intended for the Japanese market for digital dual satellite receivers/Sat-TV, and Sat-PC cards, the LNBH30 is a monolithic voltage regulator and interface IC, assembled in QFN16 (4x4 mm) specifically designed to provide the power supply to the LNB down-converter in the antenna dish or to the multi-switch box. In this application field, it offers a complete solution with extremely low component count, low power dissipation together with simple design and I²C standard interfacing.

Key Features

  • Complete interface between LNB and I²C bus
  • Built-in DC-DC converter for single 12 V supply operation and high efficiency (typ. 93% @ 0.5 A)
  • Selectable output current limit by external resistor
  • Compliant with main satellite receiver output voltage specifications
  • Low drop post regulator and high efficiency step-up PWM with integrated power NMOS allowing low power losses
  • Overload and overtemperature internal protection with I²C diagnostic bits
  • LNB short-circuit dynamic protection
  • +/- 4 kV ESD tolerant on output power pins
