Telegram : @zeusmining_presalesThe RT8537 is a constant frequency, current mode Boost-type LED driver with programmable brightness dimming control for portable devices. Located in L3, L3+ hash board U111 position. 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 RT8537 provides PWM dimming mode and 1-wire digital dimming mode for accurate LED current control from EN pin. In PWM dimming mode, the feedback reference voltage is changed with the PWM duty cycle proportionally and the available PWM frequency range is from 5kHz to 50kHz. In 1-wire digital dimming mode, it provides a programmable 32-step brightness dimming function with the EN pin setting. The RT8537 is available in the WDFN-6SL 2x2 package.
