and high efficiency are suitable for LED backlight solutions for single cell Li-ion based equipment. A precision high voltage current sink maintains the maximum LED current set by an external resistor from 10 to 31mA to drive 8 series connected LEDs. The high switching frequency supports ultra-small, low-cost filtering components. Two dimming controls are available: 32 dimming steps using S2Cwire and filtered PWM control. The frequency range of the PWM dimming extends up to 100kHz, eliminating a.
