    µModule Boost LED Driver
    and Current Source
    FEATURES DESCRIPTION True Color PWM™ with 3000:1 Dimming Ratio
    n Operates in Boost, Buck Mode or Buck-Boost Mode
    n Wide Input Voltage Range: Operation from 3V to 30V Transient Protection to 40V
    n Gate Driver for Optional PWM Dimming with
    P-channel MOSFET
    n Adjustable Frequency: 250kHz to 2MHz
    n Constant-Current and Constant-Voltage Regulatio Low Shutdown Current: <1μA
    n RoHS Compliant Package with Gold Pad Finish
    n Tiny, Low Profile (9mm × 15mm × 2.82mm)
    Surface Mount LGA Package The LTM®8042 is a complete µModule® Boost LED Driver
    specifically designed to drive LEDs up to 1A, while the
    LTM8042-1 drives up to 350mA. It combines a boost
    power topology with a unique current loop to operate as
    a constant-current source. The PWM input provides as
    much as 3000:1 LED dimming, while 10:1 analog dimming
    can be accomplished by a single resistor or analog voltage
    applied to the CTL pin. As with any boost topology, the
    LTM8042/LTM8042-1 has an uninterrupted current path
    between its input and output and is thus intolerant to a
    short-circuit or overload from the output to ground. n APPLICATIONS Display Backlighting Automotive and Avionic Lighting ...
