led驱动芯片 sun8602

description
the sun8602 is a steep-up converter designed for driving up to 39 white leds(13 strings of 3
leds each)from a 5v system rail. the sun8602 uses a current mode,fixed frequency architecture
to regulate the led current ,which is measured through an external current sense resistor. its low
101mv feedback voltage reduces power loss and improves sfficiency. the ov pin monitors the
output voltage and turns off converter if an over-voltage condition is present due to an open circuit
condition.
the sun8602 includes under-voltage lockout, current limiting and thermal overload protection
preventing damage in the event of output overload.
the sun8602 is available in small 6-pin sot23 or 8-pin qfn (2mm*2mm) package.
