RT8511AGQWA Description

Short technical summary and product information.

The RT8511AGQWA from RICHTEK is a current-mode boost WLED driver IC designed for applications like UMPC and notebook computer backlights. It integrates a 43V/1.2A power switch operating at a fixed 1MHz frequency.

 

This device supports a wide input voltage range from 2.7V to 24V and can drive up to 10 WLEDs in series with an output voltage up to 43V. The white LED current is set by an external resistor and can be controlled via PWM input for brightness dimming. The feedback voltage is regulated to 200mV typical.

 

Key features include internal soft-start, compensation, over-temperature protection, current limit protection, and programmable over-voltage protection. The RT8511AGQWA is available in compact 8-lead WDFN packages (2x2 and 3x3 mm) suitable for surface mounting.

 

It is RoHS compliant and Halogen Free, making it suitable for various electronic designs requiring efficient LED driving.
