Product Overview

The RT8511BGQW from Richtek is a 43V asynchronous boost WLED driver in 8 pin WDFN package. This is an LED driver IC can support up to 10 WLED in series. It is composed of a current mode boost converter integrated with a 43V/2.2A power switch running at a fixed 500KHz frequency and covering a wide VIN range from 2.7V to 24V. The white LED current is set with an external resistor and the feedback voltage is regulated to 200mV (typ). During operation, the LED current can be controlled by the PWM input signal in which the duty cycle determines the feedback reference voltage. For brightness dimming, the RT8511B is able to maintain steady control of the LED current. It is used in UMPC and notebook computer backlight and GPS, portable DVD backlight.
  • Wide input voltage range from 2.7V to 24V
  • High output voltage range up to 43V
  • Direct PWM dimming control and frequency from 100Hz to 8KHz
  • Internal soft-start and compensation
  • 200mV reference voltage, switching frequency of 500KHz
  • PWM dimming with internal filter, PWM dimming frequency of 8KHz, 1% minimum PWM dimming duty cycle
  • Programmable over voltage protection, Overtemperature protection
  • Minimum ON time is 60ns, 92% maximum duty cycle
  • Current limit protection
  • Operating temperature range from -40°C to 85°C
