White led power supply for large display backlight

General Features

■ Inductor switches boost controller

■ PFM mode control

■ High efficiency over wide range of input voltage

from 3.0V to 5.5V

■ Overvoltage protection with automatic restart

■ Adjustable peak current limit

QFN8 (3mm x 3mm)

■ Enable pin with possibility of PWM dimming

high as 37V and can drive up to 10 white LEDs in

series. The converter is a PFM (pulse frequency

modulation) inductor switches and can work in

discontinuous (DCM) mode operation. A minimum

OFF time of the embedded boost switch T_SWis

fixed internally and allows limiting the switching

frequency. The output current capability is 20mA

with an output voltage of 37V.

control

■ Low shutdown current <1uA

■ Small external component

■ Good load and line regulation

■ QFN 3mm x 3mm x 1mm 8 leads

Application

The regulation is done by sensing the led current

through the resistor R_LED

■ White Led supply for LCD backlight

■ Mobile phone

The device can be turned ON/OFF through the

logic enable signal pin EN. By applying a low

frequency PWM signal the LEDs can be dimmed.

■ PDA and organizers

■ Any handsets powered form 3.0V to 5.5V

The maximum peak inductor current can be

programmed by connected a resistor R_SETto the

Description

pin R_SET

STLD40D is a boost converter that operates from

3.0V to 5.5V and can provide an output voltage as
