Description

The MP3307 is a non-synchronous WLED stepupLED driver with 2.7V-to-5.5V input range. Ituses peak-current mode to regulate the LEDcurrent sensed through an external, low-sideresistor.The MP3307 features up to 2.2MHzprogrammable switching frequency which iseasy to avoid the noise interference and easy tooptimize efficiency and reduce the output filtercomponents size. To extend the dimming range,it supports both analog and PWM dimmingmode with separate input.MP3307 has LED open protection, output overvoltageprotection, cycle-by-cycle current limitprotection, and thermal shutdown protection.MP3307 is available in TSOT23-8 packagewhich is good to use in Video displays.
