Price range: $2.03
The MAX8595Z/MAX8596Z drive up to 8 white LEDswith constant current and high efficiency to provideLCD backlighting in cell phones, PDAs, and otherhandheld devices. The series connection allows theLED currents to be identical for uniform brightness andminimizes the number of traces to the LEDs. TheMAX8595Z regulates constant LED current over theentire temperature range. The MAX8596Z features anambient-temperature derating function to avoid overdrivingthe white LEDs during high ambient temperatures,enabling higher drive current below +42°C.A single Dual Mode input provides a simple means ofbrightness adjustment and on/off control. Fast 1MHzcurrent-mode PWM operation allows for small input andoutput capacitors and a small inductor while minimizingripple on the input supply/battery. Soft-start eliminatesinrush current during startup.The MAX8595Z/MAX8596Z are available in a space-saving,8-pin 3mm x 3mm TDFN package.ApplicationsCell Phones/Smartphonese-Books and SubnotebooksPDAs, Palmtops, and Wireless HandheldsWhite LED Display Backlighting
