FP6745

High-Efficiency, 40V White LED Driver

with Dimming Control

Description

Features

The FP6745 is

step-up DC/DC converter

 Wide Range for PWM Dimming, Ranging from

100Hz to 50kHz

 High Efficiency: 87%

specifically designed for driving WLEDs with a

constant current. The FP6745 can drive up 10

white LEDs in series from a Lithium Lon battery.

Series connection of LEDs provides identical LED

current for uniform brightness and minimizes the

number of traces to the LEDs. The FP6745 uses

current mode, fixed frequency of approximately

1.3MHz architecture to regulate the LED current

through an external current sense resistor. The low

feedback voltage of 195mV can minimize power

dissipation.

 Drives up to 10 WLEDs

 Fast 1.3MHz Switching Frequency

 Low 195mV Feedback Voltage

 Over Voltage Protection

 Low Profile TSOT-23-5 ,TSOT-23-6 and SOT-23-6

Packages

 RoHS Compliant

Applications

Other features include current limit protection,

thermal shutdown protection, under-voltage lockout

(UVLO), and over-voltage function, which can shut

off the device if output voltage reaches above 41V.

The FP6745 is available in space saving TSOT-23-5,

TSOT-23-6 and SOT-23-6 packages.

 Cellular Phone

 Digital Camera

 LCD Panel Backlight

 GPS Receiver

 PDA, Handheld Computer
