The STEVAL-ILD005V1 evaluation board implements a simple and cost-effective MOS-based reverse phase cut dimming solution for analog wall dimmers using a pair of STF17N62K3 power MOSFETs controlled by a triple 3-input NOR gate to effectively dim either resistive or capacitive lighting loads (i.e. halogen lamps, electronic low voltage transformers and various dimmable CFL/LED lamps). The AC analog control dimming technique employed allows for both on/off power switching and up/down dimming functions through a single linear rotary potentiometer equipped with a mechanical switch which opens the circuit at minimum setting. Control of the board is achieved using a triple 3-input NOR gate (pin-to-pin compatible with a ST's HCF4025BE 14-lead dual in-line CMOS gate logic device in plastic SO-14 micropackage) which acts as a gate driving voltage signal source, performs zero crossing detection and timing through the use of a few other passive components and diodes. https://elecena.pl/product/8157343/steval-ild005v1-trailing-edge-phase-control-rotary-wall-dimmer-based-on-stf17n62k3-power-mosfet 2017-03-26 https://elecena.pl/product/8157343/steval-ild005v1-trailing-edge-phase-control-rotary-wall-dimmer-based-on-stf17n62k3-power-mosfet 2017-09-09 https://elecena.pl/product/8157343/steval-ild005v1-trailing-edge-phase-control-rotary-wall-dimmer-based-on-stf17n62k3-power-mosfet 2020-06-05 https://elecena.pl/product/8157343/steval-ild005v1-trailing-edge-phase-control-rotary-wall-dimmer-based-on-stf17n62k3-power-mosfet 2021-04-02 https://elecena.pl/product/8157343/steval-ild005v1-trailing-edge-phase-control-rotary-wall-dimmer-based-on-stf17n62k3-power-mosfet 2022-06-12 https://elecena.pl/product/8157343/steval-ild005v1-trailing-edge-phase-control-rotary-wall-dimmer-based-on-stf17n62k3-power-mosfet 2022-06-24 https://elecena.pl/product/8157343/steval-ild005v1-trailing-edge-phase-control-rotary-wall-dimmer-based-on-stf17n62k3-power-mosfet 2023-03-26 https://elecena.pl/product/8157343/steval-ild005v1-trailing-edge-phase-control-rotary-wall-dimmer-based-on-stf17n62k3-power-mosfet 2024-06-26 https://elecena.pl/product/8157343/steval-ild005v1-trailing-edge-phase-control-rotary-wall-dimmer-based-on-stf17n62k3-power-mosfet 2024-07-14 https://elecena.pl/product/8157343/steval-ild005v1-trailing-edge-phase-control-rotary-wall-dimmer-based-on-stf17n62k3-power-mosfet 2024-08-01 https://elecena.pl/product/8157343/steval-ild005v1-trailing-edge-phase-control-rotary-wall-dimmer-based-on-stf17n62k3-power-mosfet 2024-08-18 https://elecena.pl/product/8157343/steval-ild005v1-trailing-edge-phase-control-rotary-wall-dimmer-based-on-stf17n62k3-power-mosfet 2026-03-11 https://elecena.pl/product/8157343/steval-ild005v1-trailing-edge-phase-control-rotary-wall-dimmer-based-on-stf17n62k3-power-mosfet 2026-06-04
