The RICHTEK RT8511AGQW is a current-mode boost converter designed as an LED driver IC. It supports up to 10 WLEDs in series and operates with a fixed 1MHz frequency.
Key electrical specifications include a wide input voltage range from 2.7V to 24V and a high output voltage capability of up to 43V. The integrated 1.2A power switch allows for efficient operation. The device supports direct PWM dimming control, with a dimming frequency range from 100Hz to 100kHz, enabling precise brightness control.
This LED driver IC features internal soft-start and compensation, a 200mV reference voltage, and programmable over-voltage protection. It also includes over-temperature and current limit protection for enhanced reliability. The RT8511AGQW is available in compact 8-lead WDFN packages, suitable for surface mount applications.
Applications for the RT8511AGQW include backlighting for UMPCs, notebook computers, GPS devices, and portable DVD players.
