H7230 is a built-in 100V power tube, suitable for 5-85V input high precision step-down constant current LED car light driver chip. The output current is up to 1.5A. It can realize the two-stage function switch full-bright/half-bright/burst flash cycle mode. With temperature control, with dimming feet, with output short-circuit protection function, under the condition of 5V～100V input, short-term short-circuit will not damage the power device. The function of over-temperature regulation current. When the temperature inside the chip reaches about 140°C, the output current will be automatically adjusted down.
It should be applied in a wide range of fields: LED electric car lights, motorcycle lights, car lights, bicycle lights, flashlights, flat panel display LED backlights.
H7230 product features:
a: wide input voltage range: 8V～85V, built-in 100V MOS
b: output current: 1.5A
c: fixed operating frequency: 130KHZ
d: built-in frequency jitter circuit to reduce EMI interference to other equipment
e: average Current mode sampling, higher constant current accuracy
f: 0-100 duty ratio control, no current node jump
g: output short-circuit protection, over-temperature protection
h: two function modes: full light / half light / three function cycle
I: The
H7230 chip in ESOP-8 package really effectively solves the confusion of LED car radio interference.
