LTM8005 38 VIN, 38 VOUT Boost μModule® LED Driver

Analog Devices’ drivers for high-current or high-voltage LEDs and accurate, current limited voltage regulators

Power by Linear™ / Analog Devices’ LTM8005 is a 38 VIN, 38 VOUT boost μModule (power micromodule) LED driver. This driver was 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 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 LTM8005 is suitable for automated assembly by standard surface mount equipment. It comes in a low-profile ball grid array (BGA) package enables utilization of unused space on the bottom of PC boards. The LTM8005 is ideal for high current or high voltage LEDs and accurate, current limited voltage regulators.
