White LED Driver ICs Monolithic IC MM3120

[Outline]This IC is a white LED driver IC. It is a step-up DC-DC converter IC designed to drive up to 4 LEDs with constant current and suitable for backlight drivers. It requires fewer external component count using the small packages, SON-8A and WLCSP-8B, and is ideal for small battery-powered applications.[Features]1. Enables to drive up to 4 white LEDs in a series connection2. Input voltage range 2.7 to 5.5V3. Shutdown current 0.1?A typ.4. High efficiency 82% typ.5. Luminance control PWM system6. Includes a Schottky diode and switching transistors7. Incorporates a soft start circuit8. Incorporates a current limit circuit9.
