WHITE LED STEP-UP CONVERTER

Description

Pin Assignments

The DIODES™ AP3031 is an inductor-based DC/DC boost converter

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).

Pin 1 Mark

V_IN

GND

A constant frequency 1MHz PWM control scheme is employed in this

IC, which means tiny external components can be used. Specifically,

1mm tall 4.7µH inductor and 0.47µF output capacitor for the typical

application is sufficient.

CTRL

The over output voltage protection is equipped in AP3031, which

protects the IC under open load condition. The AP3031 includes

UVLO, soft-start, current limit and OTSD to protect the circuit.

SOT-23-6

The AP3031 is available in standard SOT-23-6 package.
