RT8537 Description
The RT8537 is a current mode Boost-type LED driver with programmable brightness dimming control for portable devices. With the 40V integrated MOSFET, the RT8537 can support up to 10 LEDs in series and wide input voltage range from 2.9V to 18V. The Boost converter runs at 1.2MHz switching frequency which allows for the use of small external ponents.
