DESCRIPTION  
13/18V CONTROL WORD  
COMMUNICATION  
Intended for analog and digital satellite STB  
receivers/SatTV, sets/PC cards, the LNBEH21 is  
a monolithic voltage regulator and interface IC,  
assembled in POWER SO-20, specifically  
designed to provide the 13/18V power supply and  
the 22KHz tone signalling to the LNB  
downconverter in the antenna or to the multiswitch  
box. The LNBEH21 supports both methods of  
communication currently used, 13/18V Control  
SEMI-LOWDROP POST REGULATOR AND  
HIGH EFFICIENCY STEP-UP PWM FOR  
LOW POWER LOSS: Typ. 0.56W @ 125mA  
TWO OUTPUT PINS SUITABLE TO BYPASS
