DESCRIPTION

The ACP2727 is an inductor-based DC/DC boost

converter designed to drive LED arrays. 2A switching

current allows ACP2727 to be used in different 7' to 10'

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

A constant frequency 1MHz PWM control scheme is

employed in this IC, which means tiny external components

can be used. Specifically, 1mm tall 15μH

inductor and 10μF output capacitor for the typical

application is sufficient.

The over output voltage protection is equipped in

ACP2727, which protects the IC under open load condition.

The ACP2727 includes soft-start, current limit and

OTSD to protect the circuit.

The ACP2727 is available in standard SOT-23-6.
