Overview
19-2731; Rev 1; 10/03 KIT ATION EVALU E L B A AVAIL High-Efficiency, 26V Step-Up Converters for Two to Six White LEDs General Description The MAX1561/MAX1599 step-up converters drive up to six white LEDs with a constant current to provide backlight in cell phones, PDAs, and other hand-held devices.
The step-up converter topology allows series connection of the white LEDs so the LED currents are identical for uniform brightness.
This configuration eliminates the need for ballast resistors and expensive factory calibration.
The MAX1561/MAX1599 include an internal, high-voltage, low-RDS(ON) N-channel MOSFET switch for high efficiency and maximum battery life.
A single Dual Mode™ input provide...
