Оценочная плата, источник питания, МШУ на базе LNBH26LS, встроенный DC-DC преобразователь

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 I?C 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 I?C 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 I?C diagnostic bits
  • LNB short-circuit dynamic protection, ±4KV ESD tolerant on output power pins
