MT7613HB is a high PF, low THD, high voltage, three-segment, linear constant current IC for LED driver. The chip features high output current accuracy and no EMI issues. In addition, the output current can be set by an external resistor. 

MT7613HB adopts harmonic compensation technology, making the output current present a sine-like wave, which effectively reduces THD so that the chip can easily meet the requirements of subharmonic certification. 

MT7613HB integrates high-voltage power MOSFET and high-voltage power supply circuit, has the ability of passing EMI test easily without magnetic components such as inductor or transformer, which simplifies the peripheral circuit and reduces the BOM cost. 

MT7613HB configures line voltage compensation pin to realize excellent line regulation, constant input power achieved. With over-temperature regulation function, the chip automatically reduces the output current once IC temperature exceeds the threshold, system reliability is guaranteed.
