RT8525D

Current Mode Boost Controller

General Description

Features

z VIN Range : 4.5V to 25V

The RT8525Dis a wide input operating voltage range step

up controller. High voltage output and large output current

are feasible by using an externalN-MOSFET. The RT8525D

input operating range is from 4.5V to 25V.

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 12-Lead WDFN Package

The RT8525Dis an optimized design for wide output voltage

range applications. The output voltage of the RT8525Dcan

be adjusted by the FB pin.

z RoHS Compliant and Halogen Free
