LNBH26

Dual LNBS supply and control IC with step-up and I²C interface

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 receivers output

voltage specification (15 programmable levels)

QFN24 (4 x 4 mm)

■ Accurate built-in 22 kHz tone generator suits

widely accepted standards

■ 22 kHz tone waveform integrity guaranteed

Description

also at no load condition

Intended for analog and digital dual satellite

receivers/Sat-TV, and Sat-PC cards, the LNBH26

is a monolithic voltage regulator and interface IC,

assembled in QFN24 4x4 specifically designed to

provide the 13/18 V power supply and the 22 kHz

tone signalling to the LNB down-converter in the

antenna dishes or to the multi-switch box. In this

application field, it offers a complete solution for

dual tuner satellite receivers with extremely low

component count, low power dissipation together

with simple design and I²C standard interfacing.

■ Low drop post regulator and high efficiency

step-up PWM with integrated power N-MOS

allowing low power losses

■ LPM function (low power mode) to reduce

dissipation

■ Overload and overtemperature internal

protection with I²C diagnostic bits

■ LNB short-circuit dynamic protection

■ +/- 4 kV ESD tolerant on output power pins

Applications

■ STB satellite receivers

■ TV satellite receivers

■ PC card satellite receivers
