Device based on a high-frequency synchronous-boost topology with constant current sink is compact solution for driving single high-brightness white light emitting diodes.
Texas Instruments has released a device based on a high-frequency synchronous-boost topology with constant current sink to drive single, high-brightness white light emitting diodes (LEDs) The tiny 2 x 1.5 x 0.625mm device uses an inductive fixed-frequency PWM control scheme using small external components, minimising input ripple current for applications, such as a white LED flash for camera phones, smart phones and PDAs and other general lighting applications and reduces total solution size to less than 25mm2
