Description
The demonstration board STEVAL-CBL006V1 implements a DC-DC converter based on the device LNBH24. It gives good performance in a simple and cheap way and minimum external components are required. It includes all the functions that allow the design of a dual tuner STBs with supplying/interfacing function in accordance with the international standards. It also includes an I²C bus interface and, thanks to a fully integrated step-up DC-DC converter, it works with a single input voltage supply in the range of 8 V to 15 V. STEVAL-CBL006V1

Features
■ Complete interface between LNBs and I²C bus
■ Built-in DC-DC converter for single 12 V supply (8 V to 15 V Vin range) operation and high efficiency (typ. 93%@0.5 A)
■ Compliant with main satellite receivers output voltage specification
■ Accurate built-in 22 kHz tone generator meets widely accepted standards (patent pending)
■ Fast oscillator start-up facilitates DiSEqC™ encoding
■ Built-in 22 kHz tone detector supports bidirectional DiSEqC™ 2.0
■ Over-load and over-temperature internal protections with I²C diagnostic bits
■ Output voltage and output current level diagnostic feedback by I²C bits
■ LNB short circuit dynamic protection
■ +/- 4 kV ESD tolerant on output power pins
■ Based on LNBH24 in QFN32 package
