(MI) and the LNBA pin, thus leaving all LNB  
powering and control functions to the Master  
Receiver. This electronic switch is closed when  
the device is powered and EN pin is LOW.  
The regulator outputs can be logic controlled to  
be 13 or 18 V (typ.) by mean of the VSEL pin for  
remote controlling of LNBs. Additionally, it is  
possible to increment by 1V (typ.) the selected  
voltage value to compensate the excess voltage  
drop along the coaxial cable (LLC pin HIGH).  
DESCRIPTION  
Intended for analog and digital satellite receivers,  
the LNBK is a monolithic linear voltage regulator,  
assembled in Multiwatt-15, PowerSO-20 and  
PowerSO-10, specifically designed to provide the  
powering voltages and the interfacing signals to  
the LNB downconverter situated in the antenna  
via the coaxial cable. It has the same functionality  
of the LNBP1X and LNBP20 series, at a reduced  
output current capability. Since most satellite  
receivers have two antenna ports, the output  
voltage of the regulator is available at one of two  
logic-selectable output pins (LNBA, LNBB). When  
the IC is powered and put in Stand-by (EN pin  
LOW), both regulator outputs are disabled to  
allow the antenna downconverters to be  
supplied/controlled by others satellite receivers  
sharing the same coaxial lines. In this occurrence  
the device will limit at 3 mA (max) the backward  
current that could flow from LNBA and LNBB  
output pins to GND.  
In order to reduce the power dissipation of the  
device when the lowest output voltage is  
selected, the regulator has two Supply Input pins  
VCC1 and VCC2  
.
They must be powered  
respectively at 16V (min) and 23V (min), and an  
internal switch automatically will select the  
suitable supply pin according to the selected  
output voltage. If adequate heatsink is provided  
and higher power losses are acceptable, both  
supply pins can be powered by the same 23V  
source without affecting any other circuit  
performance.  
The ENT (Tone Enable) pin activates the internal  
oscillator so that the DC output is modulated by a  
±0.3 V, 22KHz (typ.) square wave. This internal  
For slave operation in single dish, dual receiver  
systems, the bypass function is implemented by  
an electronic switch between the Master Input pin

oscillator is factory trimmed within a tolerance of  
±2KHz, thus no further adjustments neither  
external componentsare required.  
A burst coding of the 22KHz tone can be  
accomplished thanks to the fast response of the  
ENT input and the prompt oscillator start-up. This  
helps designers who want to implement the  
DiSEqC protocols(*).  
In order to improve design flexibility and to allow  
implementation of newcoming LNB remote  
control standards, an analogic modulation input  
pin is available (EXTM). An appropriate DC  
blocking capacitor must be used to couple the  
modulating signal source to the EXTM pin. When  
external modulation is not used, the relevant pin  
can be left open.  
Two pins are dedicated to the overcurrent  
protection/monitoring: CEXT and OLF. The  
overcurrent protection circuit works dynamically:  
as soon as an overload is detected in either LNB  
output, the output is shut-down for a time Toff  
determined by the capacitor connected between  
CEXT and GND. Simultaneously the OLF pin,  
that is an open collector diagnostic output flag,  
from HIGH IMPEDANCE state goes LOW. After  
the time has elapsed, the output is resumed for a  
time ton=1/15toff (typ.) and OLF goes in HIGH  
IMPEDANCE. If the overload is still present, the  
protection circuit will cycle again through toff and  
ton until the overload is removed. Typical ton+toff  
value is 1200ms when a 4.7µF external capacitor  
is used.  
This dynamic operation can greatly reduce the  
power dissipation in short circuit condition, still  
ensuring excellent power-on start up even with  
highly capacitive loads on LNB outputs.  
The device is packaged in Multiwatt15 for  
thru-holes mounting and in PowerSO-20 for  
surface mounting. When a limited functionality in  
a smaller package matches design needs, a  
range of cost-effective PowerSO-10 solutions is  
also offered. All versions have built-in thermal  
protection against overheatingdamage.
