DESCRIPTION

SD670XSC is designed for non-isolated LED driving with Buck structure,

high constant current accuracy and high linear/load regulation available

with assistant of special sense technology.

SD670XSC integrates various protections, such as output open/short

circuit protection, cycle-by-cycle current limit protection and over

temperature protection.

The start-up current and operating current are low and highlight LED can

be driven with high efficiency in full range (85VAC~265VAC).

SD670XSC integrates high voltage power MOSFET, reducing the system

cost and the whole volume.
