MP2483  
2.5A, 55V, Programmable Frequency  
White LED Driver  
The Future of Analog IC Technology  
DESCRIPTION  
FEATURES  
The MP2483 is a 55V, 2.5A, white LED driver  
suitable for either step-down or inverting  
step-up/down applications. It achieves 2.5A  
peak output current over a wide input supply  
range with excellent load and line regulation.  
Current mode operation provides fast transient  
response and eases loop stabilization. Fault  
condition protection includes thermal shutdown,  
cycle-by-cycle peak current limiting, open  
strings protection and output short circuit  
protection.  
The MP2483 incorporates both DC and PWM  
dimming onto a single control pin. The separate  
input reference ground pin allows for direct  
enable and/or dimming control for a positive to  
negative power conversion.  
2.5A Maximum Output Current  
Unique Step-up/down Operation (Buck-  
Boost Mode)  
Wide 4.5V to 55V Operating Input Range for  
Step-Down Applications (Buck Mode)  
0.28Internal Power MOSFET Switch  
Adjustable Switching Frequency  
Analog and PWM Dimming  
0.198V Reference Voltage  
5μA Shutdown Mode  
No Minimum LED Required  
Stable with Low ESR Output Ceramic  
Capacitors  
Cycle-by-Cycle Over Current Protection  
Thermal Shutdown Protection  
Open Strings Protection  
Output Short Circuit Protection  
Available in 10-Pin 3x3 QFN Package and  
14-Pin SOIC14 Package  
The MP2483 requires a minimum number of  
readily available standard external components  
and is available in 10-pin 3mm x 3mm QFN  
package and 14-pin SOIC14 packages.  
APPLICATIONS  
General LED Illuminations  
LCD Backlight Panels  
Handheld Computers  
Automotive Internal Lighting  
Portable Multimedia Players  
Portable GPS Devices
