LTC3207/LTC3207-1

600mA Universal

Multi-Output LED/CAM Driver

FEATURES

■

DESCRIPTION

The LTC

3207/LTC3207-1 are highly integrated multi-display

LED drivers. The device contains a high-efﬁciency, low-noise

charge pump to provide power to 12 universal LED current

sources and one camera LED current source. The LTC3207/

LTC3207-1 require only ﬁve small ceramic capacitors to

form a complete LED power supply and current controller.

In addition there are two I

C addresses available.

The display currents are set by an internal precision cur-

rent reference. Independent dimming, On/Off, blinking

and gradation control for all universal current sources is

achieved via the I

C serial interface. 6-bit linear DACs are

available for adjusting brightness levels for each universal

LED current source. The CAM current source has a 4-bit

linear DAC to adjust brightness.

The LTC3207/LTC3207-1 charge pumps optimize efﬁciency

based on the voltage across the LED current sources. The

device powers-up in 1x mode and will automatically switch

to boost mode whenever any enabled LED current source

begins to enter dropout. The ﬁrst dropout switches the

IC into 1.5x mode and a subsequent dropout switches

the LTC3207/LTC3207-1 into 2x mode. The device resets

to 1x mode whenever a data register is updated via the

C port.
