MP2489  
Step Down White LED Driver with  
–
Wide 6V 60V Input Voltage  
The Future of Analog IC Technology  
DESCRIPTION  
FEATURES  
The MP2489 is a high efficiency step-down  
converter designed in continuous current mode  
for driving the high brightness Light Emitting  
Diodes (LED) from wide input voltage 6V–60V.

Internal 65V MOSFET  
Wide 6V to 60V Input Range  
≥1A Output Current  
High Efficiency (>95%)  
Hysteresis Control  
PWM & Analog Dimming  
1000:1 PWM Dimming Resolution  
Thermal Shutdown  
Inherent Open LED Protection  
Short LED Protection  
The MP2489 employs hysteretic control  
architecture to regulate a high accuracy LED  
current, which is measured through an external  
high-side current sensing resistor. Moreover,  
this control scheme provides optimized circuit  
stabilization and very quick response time  
without the loop compensation. Its low 202mV  
average feedback voltage reduces power loss  
and improves the converter efficiency.  
Available in TSOT23-5, QFN6(3x 3mm) and  
SOIC8E Packages  
APPLICATIONS  
The MP2489 implements PWM and analog  
dimming together with DIM pin.

Low Voltage Halogen Replacement  
Low Voltage General Illumination  
Automotive/Decorative LED Lighting  
Signs/Emergency Lighting  
The MP2489 includes thermal overload  
protection preventing damage in the event of an  
output overload.  
LED Backlighting  
The MP2489 is available in small QFN6 (3x  
3mm), TSOT23-5 and SOIC8E packages.  
All MPS parts are lead-free and adhere to the RoHS directive. For MPS green
