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.

IS32LT3175N/P Single-Channel Linear LED Drivers

ISSI IS32LT3175N/P Single-Channel Linear LED Drivers come with fade in/out and PWM dimming. The regulators serve as a stand-alone LED driver-configurable from 20mA to 150mA with external resistors, no microcontroller is necessary. A logic level “courtesy light” signal from the PWM pin can be interfaced to precisely drive the LED channel. The IS32LT3175P obtains a positive polarity PWM signal. In addition, the IS32LT3175N obtains a negative polarity PWM signal. The regulator integrates a 63-step fade-in and fades out the algorithm (Gamma correction). This causes the output LED current to increasingly rise up to the full source value after the EN pin is pulsed.
