RICHTEK RT8536GQW (0HR,0HW,0H3,0H0,0HL,0HS...) DFN-6,Current Mode Boost-Type LED Driver With Programmable Dimming Control
The RT8536 is a current mode Boost-type LED driver with programmable brightness dimming control for portable devices. With the 40V integrated MOSFET, the RT8536 can support up to 10 LEDs in series and wide input voltage range from 2.9V to 18V. The Boost converter runs at 600kHz switching frequency which allows for the use of small external components.
The LED current is adjustable by an external resister at FB pin and the feedback voltage is regulated to 200mV typically. The RT8536 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 RT8536 provides proper protection functions including LED open protection, input under voltage lockout, current limit and over temperature protection.
The RT8536 is available in the WDFN-6SL 2x2 package.
