Overview
MT7815B PWM/Analog dimmable Non-isolated Constant Current LED Driver DESCRIPTION MT7815B is a high precision LED constant current controller operating at critical conduction mode (CRM) with zero current switched-on and peak current switched-off.
It’s mainly targeted for non-isolated buck LED power systems and PWM/Analog dimmable application.
Critical conduction mode ensures that the MT7815B turns on the internal switch when the inductor current reaches zero, reducing the switch-on switching losses, and achieving more than 93% efficiency.
With critical conduction mode, and the input compensation, MT7815B outputs high accuracy LED current, and further achieves excellent line regulation and load regulation.
MT7815B has wide working voltage range, which is suitable for full-range AC input or 12V ~ 500V DC input voltage.
MT7815B provides various protection features to improve the system reliability, including over current protection (OCP), short circuit protection (SCP), adjustable over ...
