Description

Description

This product evaluation board implements a DC-DC converter based on the LNBH25 device used to power LNBs inside dish antennas which receive satellite TV signals. The LNBH25 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 LNBH25 evaluation board includes an I2C 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 16 V.

  • All features

    • Complete interface between LNB and I2C bus
    • Built-in DC-DC converter for single 12 V supply operation and high efficiency (typ. 93% at 0.5 A)
    • Selectable output current limit using an external resistor
    • Compliant with main satellite receiver output voltage specifications (15 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
    • LMP function (low-power mode) to reduce dissipation
    • Overload and overtemperature internal protection with I2C diagnostic bits
    • LNB short-circuit dynamic protection
    • RoHS compliant
