RT8549L規(guī)格書詳情

General 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.
