172946001

WLMDU9456001JT / 172946001 MagI3C Power Module LDHM - LED Step Down High Current Module 4.5 - 60V / 450mA / 4.5 - 60V Output DESCRIPTION The LDHM type of the MagI³C Power Module family provides a fully integrated constant current LED driver including the buck switching regulator and inductor in a package. The 172946001 offers high efficiency and delivers up to 450mA of LED current. It operates from 4.5V input voltage up to 60V and supports up to 16 LEDs in series. It is designed for fast PWM dimming for no color shift. It is available in an innovative industrial high power density TO263-7EP (10.16 x 13.77 x 4.57mm) package that enhances thermal performance and allows for hand or machine soldering. The LDHM regulator has an on-board protection circuitry to guard against thermal overstress and electrical damage featuring thermal shut-down, input under-voltage lockout and LED short-circuit protections.
