Description

Intended for analog and digital satellite receivers,

the LNBP is a monolithic linear voltage regulator,

assembled in the DFN8 (5 x 6) and IPPAK

packages, specifically designed to provide the

powering voltages and the interfacing signals to

the LNB down-converter. The regulator output

can be logic controlled for 13 V or 18 V (typ.) by

means of the EN/VSEL 3-state pin for remotely

controlling the LNB. When the IC is powered and

put in standby (EN/VSEL pin at high impedance),

the regulator output is disabled. In order to reduce

power dissipation, the LNBP10L/11L versions (on

DFN package) feature 2 supply inputs: V

at 15 V (min.) and 22 V (min.), and an internal

switch will automatically select the appropriate

supply voltage according to the selected output

voltage. The LNBP8L/9L versions (in the IPPAK

package) have only one supply input pin, which

and

must be supplied at 22 V (min.). Additionally, the

LNBP10L/11L versions have the LLC pin to

increment the selected output voltage value by 1

V (typ.) to compensate for the excess voltage

drop along the coaxial cable (LLC pin HIGH). An

analog 22 kHz modulation input pin (EXTM) is

available in the LNBP8L and LNBP10L versions.

An appropriate DC blocking capacitor must be

used to couple the modulating signal source to

the EXTM pin. The LNBP10L/11L versions are

also equipped with over-current dynamic

protection: as soon as an overload is detected the

output is shut down for the time T

determined by the capacitor connected between

the CEXT pin and GND. After the time has

dissipation in short-circuit condition, while

ensuring excellent power-on startup even with

highly capacitive loads on the LNB outputs. The

device is packaged in the IPPAK for through-hole

mounting and in the DFN8 (5 x 6) for surface

mounting. Both package solutions are offered in

two versions: with ten pins (LNBP9L/11L) to use

with the integrated 22 kHz tone generator, or with

the EXTM pin (LNBP8L/10L) to use external 22

kHz sources. All versions have built-in thermal

protection to prevent overheating damage.
