描述 Description

The RT8549L is a high efficiency Boost converter with 4-CH LED driver supporting 60V maximum output voltage. It is designed for LCD panel applications that employs LED as lighting sources. The Boost converter generates a suitable output voltage to drive four LED strings in parallel and supports up to 18 LEDs per string.



The RT8549L supports a wide input voltage range from 4.2V to 24V and provides a SMBus interface to control the LED brightness dimming mode, operating frequency and LED currents. The internal 150mΩ, 60V power switch with current-mode control provides high efficiency operation.



The RT8549L is available in the WDFN-16L 5x5 package to achieve optimized solution for PCB space.
