RT8450 Datasheet (Richtek) - High Voltage Multi-Topology LED Driver

RT8450, High Voltage Multi-Topology LED Driver

The RT8450/B is a current mode PWM regulator for LED driving applications.

With an 1.5A switch on board and wide input (4.5V to 40V) and/or output (up to 50V)ranges the RT8450/B can operate in any of the three common topologies : Buck, Boost or Buck-Boost.

With 800k/500kHz operating frequency, the e
