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
protection to prevent damage in the event of
an output overload. The MP1523 is available in
a small 5-pin SOT23 package.
