1 / 4 page STEVAL-CBL015V1 Single LNB supply and control IC DiSEqC 1.x compliant with DSQIN based on the LNBH29 in a QFN16 (4x4) Data brief Features • Complete interface between LNB and I²C bus • Built-in DC-DC converter for single 12 V supply operation and high efficiency (typ. 93% @ 0.5 A) • Selectable output current limit using an external resistor • Compliant with main satellite receiver output voltage specifications (6 programmable levels) • Accurate built-in 22 kHz tone generator suits widely-accepted standards • 22 kHz tone waveform integrity guaranteed also at no load • Low-drop post regulator and high-efficiency step-up PWM with integrated power N-MOS allowing low power losses • Overload and overtemperature internal protection with I²C diagnostic bits • LNB short-circuit dynamic protection • RoHS compliant Description This product evaluation board implements a DC- DC converter based on the LNBH29 device used to power LNB inside dish antennas which receive satellite TV signals. The LNBH29 is an integrated solution for supplying/interfacing satellite LNB modules in accordance with international standards, offering a complete solution for single- tuner satellite receivers and good performance at low cost using few external components. The LNBH29 evaluation board includes an I 2C bus interface and the internal 22 kHz tone generator (factory trimmed) is controlled by the DSQIN pin (TTL compatible), permitting immediate DiSEqC™ data encoding. A fully integrated step- up DC-DC converter allows operation with a single input voltage supply source ranging from 8 V to 17.5 V.
