General Description

The MAX1707 provides complete light management for main display backlight, subdisplay backlight (or RGB indicator), and white LED camera flash with regulated constant current up to 610mA total.

By utilizing adaptive 1x/1.5x/2x charge-pump modes and very-lowdropout current regulators, it achieves high efficiency over the full 1-cell Li+ battery input voltage range.

The 1MHz fixed-frequency switching allows for tiny external components while the regulation scheme is optimized to ensure low EMI and low input ripple.

Overview

19-3744; Rev 0; 7/05 www.DataSheet4U.com T EVALUATION KI AVAILABLE Light-Management IC with Efficient 1x/1.

Key Features

  • an internally trimmed reference to set the maximum LED current. An I2C† serial port is used for on/off control and setting the LED currents in 32 linear steps. When using the RGB indicator, the I2C port provides 32k colors and programmable rampup/down rates. The camera flash may be turned on/off by the I2C port or a separate digital logic input. Features.
  • Guaranteed 610mA Continuous Drive Capability 4 LEDs at 30mA Each for Main Display 3 LEDs at 30mA Each for Sub or RGB 400mA Total for.
