RT8525

Boost Controller with Dimming Control

General Description

Features

z VIN Range : 4.5V to 29V

The RT8525 is a wide input operating voltage range step

up controller. High voltage output and large output current

are feasible by using an externalN-MOSFET. The RT8525

input operating range is from 4.5V to 29V.

z Programmable Soft-Start Time

z Programmable Boost SW Frequency from 50kHz to

600kHz

z Output Over Voltage Protection

z Output Under Voltage Protection

z 14-Lead SOP Package

The RT8525 is an optimized design for wide output voltage

range applications. The output voltage of the RT8525 can

be adjusted by the FB pin. The PWMI pin can be used as

a digital input, allowing WLED brightness control with a

logic-level PWM signal.

z RoHS Compliant and Halogen Free

Applications

^zLCD TV, Monitor Display Backlight
