MAX1553/MAX1554 can drive white LEDs in constant current, so it can provide high-efficiency backlight for mobile phone, PDA and other portable electronic devices. MAX1553/MAX1554 contains 40V, low RDS-ON, N-channel M0SFET switch, which greatly improves the conversion efficiency and extends battery life. MAX1553 can drive 2 to 6 white LEDs to provide 480mA current limiting; the MAX1554 can drive 10 white LEDs to provides 970mA current limiting. MAX1553/MAX1554 IC provides two simple brightness adjustment methods of single analog and PWM.
