Product Overview

The STEVAL-LNBH01 is a power supply evaluation board for LNB based on the LNBH25LS. This evaluation board implements a DC-DC converter based on the LNBH25LS device. It is used to power LNBs inside dish antennas to receive satellite TV signals. The LNBH25LS is an integrated solution for supplying / interfacing satellite LNB modules in accordance with international standards. This simple solution offers a complete solution for dual tuner satellite receivers and offers high performance at low cost with a low external component count. The LNBH25LS evaluation board includes an I²C bus interface and the internal 22KHz tone generator which is factory trimmed and can be controlled by the DSQIN pin (TTL compatible) allowing immediate DiSEqC data encoding. It functions with a single input voltage supply source ranging from 8V to 16V.
  • Complete interface between LNB and I²C bus
  • Built-in DC-DC converter for single 12V supply operation and high efficiency (typ. 93% @ 0.5A)
  • Selectable output current limit by external resistor
  • Compliant w/ output voltage specifications of principal satellite receivers (15 programmable levels)
  • Accurate built-in 22KHz tone generator suits widely accepted standards
  • 22KHz tone waveform integrity guaranteed also at no load condition
  • Low drop post regulator, high efficiency step-up PWM with integrated power N-MOS allowing power loss
  • LPM function (low power mode) to reduce dissipation
  • Overload and overtemperature internal protection with I²C diagnostic bits
  • LNB short-circuit dynamic protection, ±4KV ESD tolerant on output power pins
