MT7201C 1A built-in power tube LED constant current driver
MT7201C is a continuous current mode step-down constant current driver chip. It can be effectively used to drive one or more LEDs in series when the input voltage is higher than the LED voltage. Voltage ranges from 6 volts to 40 volts and output current is adjustable up to 1 amp.
MT7201C has a built-in power switch and a high-side current circuit, and uses an external resistor to set the average current of the LED. The ADJ pin receives analog dimming and PWM and has a PWM filter circuit. The rising edge of the PWM filter circuit realizes the function of soft start. by adding an extension between the ADJ foot and the ground. When the voltage of ADJ is lower than 0.2V, the power switch is turned off, and the MT7201C enters the standby state with extremely low operating current. The MT7201C is packaged in SOT89-5.
