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.
