WHITE LED STEP-UP CONVERTER

AP3031

General Description

Features

The AP3031 is an inductor-based DC/DC boost con-

verter designed to drive LED arrays. 1.4A switching

current allows AP3031 to be used in different 7' to 10'

LCD panel backlights (3*13 LED arrays typically).

Up to 92% Efficiency

(V =9V, I =260mA)

OUT

Up to 84% Efficiency

(V =5V, I =260mA)

OUT

Fast 1MHz Switching Frequency

A constant frequency 1MHz PWM control scheme is

employed in this IC, which means tiny external com-

ponents can be used. Specifically, 1mm tall 4.7µH

inductor and 0.47µF output capacitor for the typical

application is sufficient.

Wide Input Voltage Range: 2.7V to 16V

Low 200mV Feedback Voltage

Output Over Voltage Protection

Cycle by Cycle Current Limit: 1.4A

Built-in Soft-start

Built-in Standby Mode to Achieve High Fre-

quency PWM Dimming

Built-in Thermal Shutdown Function

Under Voltage Lockout

The over output voltage protection is equipped in

AP3031, which protects the IC under open load condi-

tion. The AP3031 includes UVLO, soft-start, current

limit and OTSD to protect the circuit.

The AP3031 is available in standard SOT-23-6, TSOT-

23-6 and SOIC-8 packages.

Applications

7' to 10' LCD Panels

Digital Photo Frame

GPS Receiver

EPC

PDVD

SOT-23-6

TSOT-23-6

SOIC-8
