◆Description
LC5210D is non-isolated type driver IC for LED lighting
which can achieve high efficiency in simple circuitry. Its
compact package which includes output MOSFET and
controller, and low external components are suitable for
small lighting equipment which requires saving space, like
LED light bulb.
Its high voltage capability allows direct connection to
rectified AC supply.
Protection features ensure safety LED drive.
◆Package
