Overview

® RT7320 High Voltage Programmable Constant-Current LED Driver General Description The RT7320 is a simple and robust constant-current regulator designed to provide a cost-effective solution for driving high-voltage LEDs in LED lamp applications.
The wide input voltage range (up to 400V) allows flexible LED string design to operate with 110VRMS or 220VRMS AC input voltage.
The RT7320 allows users to set the regulated current level by connecting the pins from I1 to I5 for various LED lamps.
Parallel LED strings operation is possible with right regulated current setting on the RT7320.
In addition, the RT7320 also provides a thermal regulation protection, instead of traditional thermal shutdow...
