Product overview

Description

The STEVAL-CBL009V1 demonstration board implements a DC-DC converter based on ST’s LNBH25 device. It is used to power LNBs in dish antennas to receive satellite TV signals.

It provides good performance at low cost using a low external component count, and includes all functions needed for supplying/interfacing LNB modules in accordance with international standards.

The device includes an I2C bus interface and, thanks to a fully integrated step-up DC-DC converter, it works with a single input voltage supply 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% @ 0.5 A)
    • Selectable output current limit by external resistor
    • 22 kHz tone waveform integrity guaranteed also in no load condition
    • Low-drop post regulator and high efficiency step-up PWM with integrated power N-MOS for low power loss
    • LPM (low power mode) function to reduce dissipation
    • Overload and overtemperature internal protection with I2C diagnostic bits
    • LNB short-circuit dynamic protection
    • DiSEqC 1.x communication
    • RoHS compliant
