MP3306EG-LF-P Monolithic Power Systems

MP3306 30V, 700kHz Synchronous Step-Up White LED Driver DESCRIPTION FEATURES The MP3306 is a step-up converter designed for 3V~12V Input Voltage driving white LEDs from 3V to 12V power supply. Analog Dimming and PWM Dimming The MP3306 uses current mode, fixed frequency Output-to-Input Disconnect in Shutdown architecture to regulate the LED current, which is Mode measured through an external high-side current Programmable Open Load Shutdown sense resistor. The low 202mV feedback voltage Output Short Protection and synchronous rectification reduces power loss Low 202mV Feedback Voltage with +/-3% and improves efficiency. accuracy UVLO, Thermal Shutdown The MP3306 is turned off if an over-voltage condition is present due to an open circuit Available in 2mm x 2mm QFN12 Package condition. The output disconnect feature allows APPLICATIONS the output to be completely discharged. The MP3306 includes under-voltage lockout, current Smart Phone, MID, PDA limiting, output short protection and thermal Digital Still Cameras overload protection. Small LCD Displays The MP3306 is available in small 12-pin QFN All MPS parts are lead-free, halogen free, and adhere to the RoHS directive.
