Characteristics

• 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 450 mA of LED current. It operates from 4.5V inputvoltage 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 powerdensity TO263-7EP (10.16 x 13.77 x 4.57mm) package that enhances thermal performance and allows for handor machine soldering.
• The LDHM regulator has an on-board protection circuitryto guard against thermal overstress and electricaldamage featuring thermal shut-down, input under-voltage lockout and LED short-circuit protections.
