Texas Instruments Incorporated (TI) (NYSE: TXN) introduced today 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 mm x 1.5 mm x 0.625mm device uses an inductive fixed-frequency pulse-width modulation (PWM) control scheme using small external components, minimizing 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 25 mm2. See www.ti.com/sc07107.
