MPQ3362GJ-AEC1-P Monolithic Power Systems

MPQ3362 Single-String, 3V V , 36V V IN-MIN OUT Boost LED Driver, AEC1-Q100 DESCRIPTION FEATURES The MPQ3362 is a fixed-frequency driver, which 3V to 36V Input Voltage Range makes it well-suited for low-current and high- 4A Peak Current Limit current boost applications. The low 0.2V 0.3A Shutdown Current feedback voltage offers higher efficiency in white Low 200mV Feedback Voltage LED driver applications. Configurable 200kHz to 2.2MHz f SW Internal 80m, 40V Power Switch The device 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 MPQ3362 control loop to Under-Voltage Lockout (UVLO) Protection be optimized across a wide variety of input Open/Short LED Protection voltages. Short FB Protection Soft-Start Operation The MPQ3362 supports analog dimming and Thermal Shutdown PWM dimming on the same pin. A <2kHz input Available in a TSOT23-8 Package dimming frequency activates PWM dimming, while a >5kHz input dimming frequency activates AEC1-Q100 analog dimming. APPLICATIONS Soft start, cycle-by-cycle current limiting, and Automotive Backlighting Displays input under-voltage lockout (UVLO) protections Middle-Size Backlighting LCDs prevent sensitive external circuitry from being General Lighting damaged or overstressed 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 The MPQ3362 is available in a TSOT23-8 Assurance.
