GENERAL DESCRIPTION  
FEATURES  
The EV1528DQ-00A evaluation board is  
designed for driving up to nine (9) series  
WLEDs from a single cell Lithium Ion battery.  
The board is set up to obtain 20mA LED  
current. The current can be adjusted by varying  
the resistor R1.  
2.7V to 5.5V Input Voltage Range  
Drives up to 9 Series White LEDs  
Analog and Digital PWM Brightness Control  
Through BRT  
Surface-Mount Components  
Fully Assembled and Tested  
The MP1528 uses current limited, variable  
frequency architecture to regulate the LED  
current while maintaining high efficiency. The  
BIAS pin measures the output voltage and turns  
off the converter if an over voltage condition is  
present to prevent damage due to an open  
circuit condition. The LED current is measured  
with an external current sense resistor. The low  
0.4V full-scale regulation threshold and 0.4  
power switch minimize power loss to improve  
efficiency. Either a DC voltage or a PWM signal  
at the BRT input can control the LED  
brightness.
