Datasheet Summary
LC5223D and LC5226D
Off-Line DC / DC LED Driver ICs
Features and Benefits
Description
- Buck and buck-boost topology; selectable by peripheral
LC5220 series is a non-isolating, simple and efficient LED circuit structure driver. The high voltage capability allows direct connection
- Built-in fixed reference voltage limiting constant current to a wide range of supply voltages ranging from 25 to 400 V control; high precision regulator improves current
(remended). The LC5220 uses constant current mode precision and simplifies setting of current level
- Sleep function, with latch mode; input high, 3 V or more, on REF pin turns off IC output to LEDs
- Enable function; input low on...
