H5031 is a led multipurpose 3-line/4-line light flashing at ic
Led 3-line brake lights special chip, low-light drive, high-altitude brake, low-cost h5031, low-pressure constant flow, integrated high-light, low-light, high-flash
H5031 is a pwm mode of work that is efficient and simple and applies to a high-precision led constant current drive chip input of 3. 6-100 v, with output current up to 5a。
H5031 supports low-light priority and allows for three functional transitions through mode1/2/3 to three functional modes: full brightness, half brightness, bursting, full brightness/half brightness/flash cycle。
H5031 the working frequency is fixed to around 130khz, with a dithered frequency circuit that reduces emi interference with other equipment. An average current sampling model is also used to increase current accuracy in case of wide input voltage。
H5031 with output short circuit protection, short circuits do not damage power units under 5-150 v input conditions。
H5031 also has the function of temperature regulation of currents. When the internal temperature of the chip reaches about 140°c, the output current is automatically lowered。
