LNBK20PD-TR

The LNBK20PD-TR is a kind of LNB supply and control voltage regulator (parallel interface). It is intended for analog and digital satellite receivers. Besides, it is available in PowerSO-20 package for surface mounting. All versions have built-in thermal protection against overheatingdamage.

There are some features as follows: (1) complete interface for two LNBs remote supply and control; (2) LNB selection and standby function; built-in tone oscillator factory trimmed at 22 KHz; (3) fast oscillator start-up facilitates DiSEqCTM encoding; (4) two supply inputs for lowest dissipation; (5) bypass function for slave operation; (6) LNB short circuit protection and diagnostic; (7) auxiliary modulation input extends flexibility; (8) cable length compensation; (9) internal over temperature protection; (10) backward current protection.

What comes next is about the absolute maximum ratings. (1): Vi (DC input voltage (VCC1, VCC2, MI)) is 28 V; (2): Io (output current (LNBA, LNBB)) is internally limited; (3): Vi (logic input voltage (ENT, EN, OSEL, VSEL, LLC)) is from -0.5 to 7 V; (4): ISW (bypass switch current) is 900 mA; (5): Ptot (power dissipation at Tcase<85) is 14 W; (6): Tstg (storage temperature range) is from -40 to 150; (7): Top (operating temperature range) is from -40 to 125.
