Semtech Corp., has utilized its patent-pending, smart Automatic Dropout Prevention (ADP) technology to develop the industry’s first smart current sink LED backlighting platform , SC667 and SC668,with on-chip digital lighting effects for high-end handheld displays.

This new platform is designed to replace boost converters and charge pumps in high-end handhelds, while providing high-quality display backlighting.

With ADP technology, the new current sinks are capable of reducing the total parts count and extend battery life compared to boost converters or charge pumps, and offer far superior illumination quality compared to conventional current sink drivers.

What’s more, on-chip digital lighting effects provide the flexibility to incorporate fade, breathe and blink effects without changing the firmware.

Aside from these, the devices also integrate a number of functions to enable high-end features on portables, including an ambient light sensing/control circuit that sets backlight brightness based on surrounding lighting conditions.

A PWM dimming interface that incorporates a digital low-pass filter is also included, providing the capability to perform content-adaptive brightness control (versus “always-on” illumination).
