FP6737/A

Built-In OVP White LED Step-Up

Converter in Tiny Package

Description

Features

The FP6737/A is a step-up DC/DC converter

specifically designed to drive white LEDs with a

constant current. The device can drive two to

seven LEDs in series from a Li-Ion cell. Series

connection of the LEDs provides identical LED

current resulting in uniform brightness and

eliminating the need for ballast resistors. The

FP6737/A switches at 1.2MHz, allowing the use of

tiny external components. The output capacitor can

be as small as 0.22μF for saving space and cost

versus alternative solutions. A low 250mV/104mV

feedback voltage minimizes power loss in the current

setting resistor for better efficiency.

● Inherently Matched LED Current

● High Efficiency: 87%

● Drives up to Seven LEDs from a 3.2V Supply

● 33V Internal Switch

● Fast 1.2MHz Switching Frequency

● Use Tiny 1mm Tall Inductors

● Need only 0.22µF Output Capacitor

● Low Profile SOT-23-6 and TSOT-23-6 Packages

● Built-In Open Circuit Protection

● Over Voltage Protection

● RoHS Compliant

Applications

● Cellular Phone

● Digital Camera

● MP3 Player

The FP6737/A is available in low profile SOT-23-6

and TSOT-23-6 packages.

● GPS Receiver

● PDA, Handheld Computer
