Rohm has launched a device that will simplify the design of mobile phones requiring full colour backlights by delivering the increased voltages and driving functionality demanded by white LEDs.
Rohm's BD6155FVM white LED driver IC combines an integrated boost charge pump with fixed current LED driver circuitry to minimise the need for discrete driver and step-up circuitry.
The device, which operates from voltages down to 2.9V, can be used to step up mobile phone battery voltages to deliver an output of up to 5.6V.
Supplied in a compact 8-pin MSOP package, the BD6155FVM has dimensions of just 2.8 x 2.8 x 0.9mm and has a typical power dissipation of 350mW.
Operating temperature is rated at -25 to 75C.
