The LM3530 white-LED driver with dynamic display backlight control can supply up to 29.5 mA of power to 11 LEDs from a single-cell lithium-ion battery. Offered in a 12-bump micro SMD package, the device employs sophisticated ambient light-sensing algorithms and content-adjustable backlighting.
Logarithm and linear LED brightness mapping provides flicker-free dimming, while a fixed-frequency 500-kHz boost converter provides high efficiency over the LED current range. The driver is programmable via an I2 C compatible interface. ($1.99 ea/1,000 — available now.)
