This evaluation board implements a DC-DC converter based on the LNBH25S device. It is used to power LNBs inside dish antennas to receive satellite TV signals. The LNBH25S is an integrated solution for supplying / interfacing satellite LNB modules in accordance with international standards. It is a simple and complete solution for dual tuner satellite receivers and provides high performance at low cost with a low external component count. The LNBH25S evaluation board includes an I²C bus interface and an internal 22 kHz tone generator which is factory trimmed and can be controlled by the DSQIN pin (TTL compatible), allowing immediate DiSEqC™ data encoding. Thanks to a fully integrated step-up DC-DC converter, it functions with a single input voltage supply source ranging from 8 V to 16 V. https://elecena.pl/product/8157607/steval-lnbh02-power-supply-evaluation-board-for-lnb-based-on-the-lnbh25s 2017-03-27 https://elecena.pl/product/8157607/steval-lnbh02-power-supply-evaluation-board-for-lnb-based-on-the-lnbh25s 2017-09-09 https://elecena.pl/product/8157607/steval-lnbh02-power-supply-evaluation-board-for-lnb-based-on-the-lnbh25s 2020-06-05 https://elecena.pl/product/8157607/steval-lnbh02-power-supply-evaluation-board-for-lnb-based-on-the-lnbh25s 2021-04-02 https://elecena.pl/product/8157607/steval-lnbh02-power-supply-evaluation-board-for-lnb-based-on-the-lnbh25s 2022-06-12 https://elecena.pl/product/8157607/steval-lnbh02-power-supply-evaluation-board-for-lnb-based-on-the-lnbh25s 2022-06-24 https://elecena.pl/product/8157607/steval-lnbh02-power-supply-evaluation-board-for-lnb-based-on-the-lnbh25s 2025-06-27 https://elecena.pl/product/8157607/steval-lnbh02-power-supply-evaluation-board-for-lnb-based-on-the-lnbh25s 2026-03-02
