Würth Elektronik LDHM Power Module
Würth Elektronik MagI³C LDHM Step-Down High Current Module features a fully integrated current driver with passives all in one package. This LDHM driver module provides a ready-made solution that is highly efficient and can be used for a variety of single-string LED lighting applications. Würth MagI³C LDHM Step-Down High Current Module can dim the LEDs with an external PWM signal for easy brightness controlling. It operates at a constant switching frequency of 800kHz for low electromagnetic interference (EMI) and is designed according to the standard EN55015. The 178946001 Evaluation Board efficiently evaluates this LDHM module.Features
