About This Product

■Summary

MP3370 is a fixed frequency boost converter with current source. Ideal for medium and high current boost LED driver applications. The MP3370 uses an integrated 100mΩ/50V low-side MOSFET to adjust the output voltage up to 38V to drive more LEDs. Peak current mode regulation and external compensation components optimize the MP3370's control loop over a variety of input voltage, output voltage, and load current applications. Internal soft-start, cycle-by-cycle current limiting, and input undervoltage lockout prevent undue stress and damage to sensitive external circuitry during start-up or fault conditions. The MP3370 supports PWM dimming and analog dimming for flexible dimming applications. The MP3370 is available in a thermally enhanced, exposed pad SOIC8-EP package.

■Features and benefits

・3.5V to 36V input range ・Peak current limit exceeding 3A ・Internal 100mΩ 50V power switch ・Analog/PWM dimming ・High efficiency ・Low voltage malfunction prevention function protection ・LED open/short circuit protection ・Inductor/diode short circuit protection ・43.5V overvoltage protection ・Soft start operation ・Thermal shutdown ・SOIC8-EP package

■Available product numbers

・MP3370GN-P MP3370GN-Z ・Part numbers ending in P and Z are the same part. P and Z indicate reel size only
