DESCRIPTION
Intended for analog and digital satellite receivers,
the LNBP is a monolithic linear voltage regulator,
assembled in HeptawattTM, specifically designed
to
provide
the
powering
voltages
and
the
interfacing signals to the LNB down-converter.
The regulator output can be logic controlled to be
13V or 18V (typ.) by mean of the VSEL pin for the
remote controlling of the LNB. In order to reduce
the power dissipation of the device when the
lowest output voltage is selected, the regulator
has 2 supply inputs (VCC1 and VCC2). They must
be powered respectively at 15V (min.) and 22V
(min.), and an internal switch will automatically
select the appropriate supply voltage according to
the selected output voltage.
The TONE pin (only for the LNBP9 version)
activates the internal oscillator so that the DC
output is modulated by a 22KHz square wave.
This internal oscillator is factory trimmed within a
tolerance of +/- 2KHz, thus no further adjustment
or external components are required.
A burst coding of the 22KHz tone can be
accomplished thanks to the fast response of the
TONE input and the prompt oscillator start-up.
This helps designers which want to implement the
DiSEqCTM protocols.
In order to improve design flexibility and to allow
implementation of other LNB remote control
standards, an analogic modulation input pin
(EXTM) is available (LNBP8 version only). An
appropriate DC blocking capacitor must be used
to couple the modulating signal source to the
EXTM pin.
Both versions integrate thermal and short circuit
protection.
The device is packaged in Heptawatt for an easy
thru-hole mounting. If an 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.
When the IC is powered and put in Stand-by (EN
pin LOW), the regulator output is disabled and the
IC power consumption is reduced to 300A typ.
