Overview
19-2783; Rev 2; 8/05 EVAALVUAAILTAIOBNLEKIT High-Efficiency Step-Up Converters for White LED Main and Subdisplay Backlighting MAX1582/MAX1582Y General Description The MAX1582/MAX1582Y drive up to six white LEDs in series with a constant current to provide display backlighting for two (main and sub-) displays in cell phones and other handheld devices.
This configuration eliminates the need for ballast resistors and expensive factory calibration.
The proprietary dual-output, step-up pulse-width modulation (PWM) converter includes a low RDSON n-channel MOSFET switch for high efficiency and maximum battery life.
The MAX1582/MAX1582Y utilize 1MHz current-mode PWM control to allow small input and output capacitors and a small inductor, while minimizing ripple on the input supply and avoiding interference to sensitive circuitry in the equipment.
Integrated overvoltage protection (27V for the MAX1582 and 18V for the MAX1582Y) eliminates the need for an external zener diode to protect the ...
