Product Details

The LTM8005 is a 38VIN, 38VOUT boost μModule (power micromodule) LED driver designed to regulate current or voltage and is ideal for driving LEDs. The fixed frequency and current mode architecture result in stable operation over a wide range of supply and output voltages. Spread spectrum frequency modulation (SSFM) can be activated for improved electromagnetic compatibility (EMC) performance. The ground-referred voltage FB pin serves as the input for several LED protection features, and also allows the converter to operate as a constant voltage source. The PWM input provides LED dimming ratios of up to 3000:1, and the CTRL inputs provide additional analog dimming capability.

The low profile package enables utilization of unused space on the bottom of PC boards. The LTM8005 is packaged in thermally enhanced, compact over-molded Ball Grid Array (BGA) package suitable for automated assembly by standard surface mount equipment. The LTM8005 is RoHS compliant.

Applications

  • High Power LED, High Voltage LED
  • Accurate Current-Limited Voltage Regulators
