MP3370
Single String, 38V Vout
Boost LED Driver with Current Source
DESCRIPTION
The MP3370 is a fixed-frequency boost
converter with current source. It is ideal for
medium-to-high current boost LED driver
applications.
The MP3370 regulates the output voltage up to
38V to drive more LEDs with an integrated
100mΩ/50V low-side MOSFET. The peak
current-mode regulation and external
compensation components allow the MP3370
control loop to be optimized over a wide variety
of input voltage, output voltage, and load
current applications. The internal soft-start,
cycle-by-cycle current limiting and input under
voltage lockout prevent overstressing or
damage to sensitive external circuitry at start-up
and fault conditions.
The MP3370 supports PWM dimming and
analog dimming for flexible dimming
applications.
The MP3370 is available in the thermally
enhanced SOIC8-EP package with exposed
pad.
