MP24830  
4.5V – 90V, Programmable Frequency  
White LED Driver  
The Future of Analog IC Technology  
DESCRIPTION  
FEATURES  
The MP24830 is a 90V white LED driver  
suitable for either step-down or inverting  
step-up/down applications. It supports a wide  
input range with excellent load and line  
regulation. Its programmable current limit  
provides customized applications with a wide  
power range. Current mode operation provides  
a fast transient response and eases loop  
stabilization. Fault condition protection includes  
thermal shutdown, cycle-by-cycle peak-current  
limiting, open-string protection, and output  
short-circuit protection.  
•
•
Programmable Maximum Output Current  
Unique Step-Up/Down Operation (Buck-  
Boost Mode)  
Wide 4.5V-to-90V Operating Input Range  
for Step-Down Applications (Buck Mode)  
Adjustable Switching Frequency  
Analog and PWM Dimming  
0.2V Reference Voltage

10μA Shutdown Mode  
No Minimum LED Quantity Required  
Stable with Low ESR Output Ceramic  
Capacitors  
The MP24830 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.

Cycle-by-Cycle Over-Current Protection  
Thermal Shutdown Protection  
Open-String Protection  
Output Short-Circuit Protection  
Available in 14-Pin SOIC and QFN  
Packages  
The MP24830 requires a minimal number of  
readily-available external components. It is  
available in 14-pin SOIC and QFN packages.
