NCP5612
High Efficiency Ultra Small
Thinnest White LED Driver
The NCP5612 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
• Support the Single Wire Serial Link Protocol
• Peak Efficiency 90% with 1x and 1.5x Mode
• Programmable Dimming ICON Function
• Built−in Short Circuit Protection
• Provides 16 steps Current Control
• Controlled Start−up Inrush Current
• Built−in Automatic Open Load Protection
• Tight 0.2% Matching Tolerance
• Accurate 1% Output Current Tolerance
• Smallest Available Package on the Market
• This is a Pb−Free Device

6. The overall output current tolerance depends upon the accuracy of the external resistor. Using 1% or better resistor is recommended.
7. The external circuit must not force the IREF pin voltage either higher or lower than the 600 mV specified.
DIGITAL PARAMETERS SECTION (Typical values are referenced to TA = +25°C, Min & Max values are referenced −40°C to +85°C
ambient temperature, operating conditions 2.85 V < Vbat < 5.5 V, unless otherwise noted.) Note: Digital inputs undershoot < − 0.30 V to
ground, Digital inputs overshoot < 0.30 V to VBAT.
