Introduction






The FP6755 is a step-up DC/DC converter specifically designed for driving WLEDs with a constant current. The FP6755 can drive up 8 white LEDs in series from a Lithium Lon battery. Series connection of LEDs provides identical LED current for uniform brightness and minimizes the number of traces to the LEDs. The FP6755 uses current mode, fixed frequency of approximately 1.3MHz architecture to regulate the LED current through an external current sense resistor. The low feedback voltage of 195mV can minimize power dissipation.
Other features include current limit protection, thermal shutdown protection, under-voltage lockout (UVLO), and over-voltage function, which can shut off the device if output voltage reaches above 29V.
The FP6755 is available in space saving SOT-23-6 & TDFN-6 (2mm×2mm) packages.
