DESCRIPTION

MT7212 is a continuous mode inductive step-down converter, designed for driving single or multiple series connected LEDs efficiently from a voltage source higher than the total LED chain voltage. The device operates with a wide input supply voltage up to 80V and provides an externally adjustable output current, and it is suitable for high input voltage and output power applications. MT7212 combines a 80V power MOSFET. It sets the average output current by the low-side output current sense circuit. MT7212 provides various protection features to improve the system reliability, including over temperature regulation (OTR), and over temperature shutdown (OTP), LED short/open protection, etc. Typical Application Circuit
