Datasheet Summary
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.
