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.
