Overview

RT8453B 1.
5A, 500kHz, 40V High Voltage Buck LED Driver General Description The RT8453B is a buck current mode PWM regulator for LED driving applications.
It provides an integrated 1.
5A switch and can be operated with a wide input voltage range from 4.
5V to 40V.
With a 500kHz operating frequency, the RT8453B allows all external inductor and input/output capacitors to be small.
High efficiency is achieved with its 190mV current sensing capability.
Dimming can be either analog or PWM digital signal driven.
The RT8453B is available in a small SOP-8 (Exposed pad) package.
Ordering Information RT8453B Package Type SP : SOP-8 (Exposed Pad-Option 2) Lead Plating System G : Green (Halogen Free and...
