Product Details
MT7004B High frequency PWM dimming, boost LED driver chip
The MT7004B is a boost LED driver chip that can drive up to 39 LEDs (3 strings and 13 parallels) from a 5V power supply.
The MT7004B uses a fixed operating frequency and current mode to adjust the LED current through an external current sense resistor. The 110mV feedback voltage effectively reduces power consumption and improves efficiency. The MT7004B has an open-circuit protection function. Once the OV pin detects an overvoltage condition, the chip will shut down the converter. At the same time, MT7004B also includes under-voltage lockout, current limiting and overheating protection and other abnormal protections to improve the reliability of the system.
