DESCRIPTION

MT7223 is a high efficiency and high precision

step-down constant current LED driver with an

integrated 90V MOS switch.

MT7223 uses fixed-off-time peak current control

scheme, the off-time can be adjusted by

changing the external capacitor, and the

operation frequency also can be adjusted

according to the need of customer.

MT7223 regulates the current flowing through

LEDs to set the luminance of LEDs by changing

the external current sense resistor, on the other

hand, the luminance of LEDs also can be

regulated by a PWM signal applied to DIM pin.

DIM pin can also achieve linear dimming.

MT7223 integrates VDD Zener Diode and over

temperature protection, etc. to reduce the

peripheral components and improve the system

reliability

.
