® RT8450, B High Voltage Multi-Topology LED Driver General Description 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, 500kH- operating frequency, the external PWM inductor and input, output capacitors can all be small. High efficiency is achieved by a 190mV current sensing
