MP3362 Single-String, 3V Minimum V , 36V V , IN OUT Boost LED Driver DESCRIPTION FEATURES The MP3362 is a fixed-frequency converter ideal 3V to 36V Input Voltage Range for low-current and high-current boost 4A Peak Current Limit applications. The low 0.2V feedback voltage 0.3A Shutdown Current offers higher efficiency in white LED driver Low 200mV Feedback Voltage applications. Configurable 200kHz to 2.2MHz f SW Internal 80m, 40V Power Switch The MP3362 regulates the output voltage up to High Efficiency 36V with efficiency as high as 95%. Current mode regulation and external compensation Analog and PWM Dimming components allow the MP3362 control loop to be Under-Voltage Lockout Protection optimized across a wide variety of input voltages. Open/Short LED Protection Short FB Protection The MP3362 supports analog dimming and Soft-Start Operation PWM dimming on the same pin. A <2kHz input Thermal Shutdown dimming frequency initiates PWM dimming, Available in a TSOT23-8 Package while an >5kHz input initiates analog dimming. Soft start, cycle-by-cycle current limiting, and APPLICATIONS input under-voltage lockout prevent Medium-Sized LCD Backlighting overstressing or damaging sensitive external General Lighting circuitry during start-up or potential overload current conditions. All MPS parts are lead-free, halogen-free, and adhere to the RoHS directive. For MPS green status, please visit the MPS website under Quality Assurance.
