Data Sheet 27448.1 8284 ADVANCE INFORMATION (Subject to change without notice) December 22, 2000 TWO-OUTPUT LNB SUPPLY AND CONTROL-VOLTAGE REGULATOR Intended for analog and digital satellite receivers, the low noise block A8284SLB converter regulator (LNBR) is a monolithic linear and switching voltage regulator designed to provide power and interface signals to the LNB OSEL 1 24 EXTM downconverter via the coaxial cable. Because most satellite receivers have two antenna ports, the output voltage of the regulator is available at one of two OLF 2 23 VINT logic-selectable output terminals (LNBA, LNBB). If the device is in stand-by mode (EN terminal LOW), both regulator outputs are disabled, allowing the VBULK 3 22 PUMPX antenna downconverters to be supplied and controlled by other satellite CHARGE PUMP LNBB 4 YNC 5 GND 6 RGND 7 OSENSE 8 TLNBA 99 CLX 10 BUCK VOLTAGE CONTROL AVIN 11 FTCAP 12 REG. 21 VPUMP 20 CPUMP 19 GND 18 GND 17 ENT 16 EN 15 VSEL0 14 VSEL1 13 LLC.
