Pregled izdelka

The STEVAL-LNBH04 is a power supply evaluation board for LNB based on the LNBH26LS. This evaluation board implements a DC to DC converter based on the LNBH26LS device. It is used to power LNBs inside dish antennas to receive satellite TV signals. The LNBH26LS is an integrated solution for supplying and interfacing satellite LNB modules in accordance with international standards. This simple and complete solution for dual tuner satellite receivers offers high performance at low cost and low external component count. The LNBH26LS 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
