MP3370 Single String, 38V Vout Boost LED Driver with Current Source DESCRIPTION FEATURES The MP3370 is a fixed-frequency boost Input Range of 3.5V to 36V converter with current source. It is ideal for More than 3A Peak Current Limit medium-to-high current boost LED driver Internal 100m 50V Power Switch applications. Analog/PWM Dimming High Efficiency The MP3370 regulates the output voltage up to Under-Voltage Lockout Protection 38V to drive more LEDs with an integrated LED Open/Short Protection 100m/50V low-side MOSFET. The peak current-mode regulation and external Inductor/Diode Short Protection compensation components allow the MP3370 43.5V Over-Voltage Protection control loop to be optimized over a wide variety Soft-Start Operation of input voltage, output voltage, and load Thermal Shutdown current applications. The internal soft-start, SOIC8-EP Package cycle-by-cycle current limiting and input under voltage lockout prevent overstressing or APPLICATIONS damage to sensitive external circuitry at start-up Middle Size LCD Backlighting and fault conditions. General Lighting All MPS parts are lead-free, halogen-free, and adhere to the RoHS The MP3370 supports PWM dimming and directive. For MPS green status, please visit the MPS website under analog dimming for flexible dimming Quality Assurance.
