NCP5602 Datasheet, PDF (1/12 Pages) ON Semiconductor – High Efficiency Ultra Small Thinnest White LED Driver

NCP5602
High Efficiency Ultra Small
Thinnest White LED Driver
The NCP5602 product is a dual output LED driver dedicated to the
LCD display backlighting.
The built−in DC−DC converter is based on a high efficient charge
pump structure with operating mode 1x and 1.5x. It provides a peak
87% efficiency together with a 0.2% LED to LED matching.
Features
• 2.7 to 5.5 V Input Voltage Range
• 87% Peak Efficiency with 1x and 1.5x Mode
• ICON Function Implemented
• Built−in Short Circuit Protection
• Provides Two Independent LED Drives
• Support I2C Protocol
• Smallest Available Package on the Market
• Tight 0.2% LED to LED Matching
• This is a Pb−Free Device
