38V Boost µModule Regulator for

LED Drive with 10A Switch

FEATURES

DESCRIPTION

The LTM^®8005 is a 38V , 38V

boost µModule (power

Wide Input Voltage Range: 5V to 38V

Supports Boost or SEPIC Power Topologies

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) perfor-

mance. 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.

Adjustable LED Current Up to 1.6A

40V 10A Internal Power Switch

Wide Temperature Range: –40°C to 150°C

Input and Output Current Reporting

Internal Switch for PWM and Output Disconnect

Internal Spread Spectrum Frequency Modulation

3000:1 True Color PWM™ Dimming

Open LED Protection with OPENLED Flag

Short-Circuit Protection and SHORTLED Flag

Soft-Start with Programmable Fault Restart Timer

9mm × 11.25mm × 2.22mm BGA

The low profile package enables utilization of unused

space on the bottom of PC boards. The LTM8005 is pack-

aged in thermally enhanced, compact over-molded Ball

Grid Array (BGA) package suitable for automated assem-

bly by standard surface mount equipment. The LTM8005

is RoHS compliant.
