LNBH29

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

Datasheet - production data

 Low-drop post regulator and high efficiency

step-up PWM with integrated power N-MOS

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

Applications

QFN16 (4x4) / (3x3)

 STB satellite receivers

 TV satellite receivers

 PC card satellite receivers

Features

Description

 Complete interface between LNB and I²C bus

Intended for analog and digital satellite

 Built-in DC-DC converter for single 12 V supply

operation and high efficiency (typ. 93% @

0.5 A)

receivers/Sat-TV and Sat-PC cards, the LNBH29

series is a monolithic voltage regulator and

interface IC, assembled in QFN16 (3x3) and

QFN16 (4x4) specifically designed to provide the

13 / 18 V power supply and the 22 kHz tone

signaling 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 a simple design and I²C

standard interfacing.

 Selectable output current limit by external

resistor

 Compliant with main satellite receiver output

voltage specifications

 Accurate built-in 22 kHz tone generator suits

widely accepted standards

 EXTM pin, auxiliary 22 kHz modulation input

(LNBH29E) extends design flexibility

 22 kHz tone waveform integrity guaranteed

also at no load condition
