describe

MT7860 is a high power factor step-down type that operates in quasi resonant mode (QRM), greatly reducing current and pressure stress, while improving efficiency and electromagnetic interference resistance performance. By utilizing Meixinsheng's unique quasi full cycle detection of LED output current, the accuracy of LED output current is ensured. MT7860 achieves intelligent dimming by decoding PWM signals and analog LED current signals. The encoder achieves high precision and consistency in LED current. When the light level is low, the PWM control method seamlessly transitions from quasi resonant mode to pulse frequency modulation mode (PFM) with low output current and low switching losses.

In addition, MT7860 also implements various open circuit protection (OVP), cycle by cycle overcurrent protection short circuit protection (SCP), and over temperature compensation to ensure operation.
