Maximizing IC Performance
MT7963
High Accuracy, Dual Winding PSR AC-DC LED Driver
DESCRIPTION
MT7963 is a PWM controller for AC-DC LED
lighting. With primary side sensing and
regulation technology, no secondary side
feedback circuit is needed. Further, the loop
compensation components are also eliminated
while maintaining system stability. Integrated
with 650V power switch simplifies the system
design and improves the reliablity.
With Maxic’s proprietary current regulation
technique, the MT7963 achieves ±5% accuracy
of LED current along with excellent line
regulation and load regulation.
MT7963 provides plenty of protections, such as
such as over current protection(OCP), short
circuit protection (SCP),over voltage protection
(OVP) and over temperature protection(OTP),etc,
to ensure system reliability.
