LNBH26L  
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 receiver output  
voltage specification (8 programmable levels)  
QFN24 (4x4 mm)  
Accurate built-in 22 kHz tone generator suits  
widely accepted standards  
22 kHz tone waveform integrity guaranteed  
also at no load condition  
Low-drop post regulator and high efficiency  
step-up PWM with integrated power N-MOS  
allowing low power losses  
Description  
Intended for analog and digital DUAL satellite  
receivers/Sat-TV, Sat-PC cards, the LNBH26L 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 an extremely  
low component count and low power dissipation  
together with simple design and I²C standard  
interfacing.  
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
