MP1523规格书详情
DESCRIPTION
The MP1523 is a 5-pin SOT23 step-up converter designed for driving up to six (6) series white LEDs from a single-cell Lithium Ion battery. The MP1523 uses a current limited, variable frequency architecture to regulate the LED current, which is measured through an external current sense resistor. Its low 0.4V feedback threshold reduces power loss and improves efficiency. To prevent damage due to an open circuit condition, the BIAS pin can measure the output voltage and turn off the converter if an over-voltage condition is present.
The MP1523 includes under-voltage lockout, current limiting, and thermal overload protection to prevent damage in the event of an output overload. The MP1523 is available in a small 5-pin SOT23 package.
