GENERAL DESCRIPTION
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.
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.
