MP3307GJ-P Monolithic Power Systems

MP3307 2.7V-5.5V Input, 24V OVP, Programmable Fsw, White LED Driver The Future of Analog IC Technology FEATURES DESCRIPTION 2.7V to 5.5V Input Voltage The MP3307 is a non-synchronous WLED step- Analog Dimming with >20kHz Input Signal up driver with a 2.7V to 5.5V input range. It Direct PWM Dimming Mode with 100Hz to uses peak current mode to regulate the LED current sensed through an external low-side 2kHz Input Signal resistor. Up to 2.2MHz Programmable Switching Frequency The MP3307 features up to 2.2MHz of Low 200mV Feedback Voltage with 1% programmable switching frequency, making it Accuracy at Room Temperature easy to avoid noise interference, optimize 24V Open-Load Protection Threshold efficiency, and reduce the output filter UVLO and Thermal Shutdown component size. To extend the dimming range, Cycle-by-Cycle Over-Current Protection both analog and PWM dimming modes are Available in a TSOT23-8 Package supported with a separate input. The MP3307 has LED open protection, output APPLICATIONS over-voltage protection, cycle-by-cycle current- Video Displays limit protection, and thermal shutdown In-Car LCD Infotainment protection. Tablets The MP3307 is available in a TSOT23-8 All MPS parts are lead-free, halogen-free, and adhere to the RoHS directive. For package, which is ideal for use in video displays.
