9 Lamp, 36V Precision White LED DriverThe MP1528 is a step UP Converter designed for driving up to nine (9) series White LEDs (LED) from a single cell Lithium-Ion battery. It regulates the LED current and includes an Analog input for varying the LED brightness.
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 0.63, power Switch minimize power loss.
The MP1528 is available in an 8 pin MSOP and a tiny 6 pin 3mm x 3mm QFN packages.
