DESCRIPTION
The WS9055X is a highly integrated controller, it adopts
the non-vcc capacitor technology to dramaticlly enhance
the cost-effecitve system BOM.WS9055X builds in the
accurate constant current controlling to achieve the good
line and output regulation.
The WS9055X operates in Bondary Conducted
Mode(BCM) to get ease EMI designing and high system
efficiency.
The WS9055X integrates the high voltage MOSFET and
the start-up circuit without the external vcc
capacitor,WS9055X is suitable for compact and
cost-effective non-dimmable system design.
The WS9055X build-in multiple protections: OCP,UVLO,
high temperature foldback, Output Short-circuit Protection
and open-circuit protection.
WS9055X is available in SOP-7 and DIP-7 package.
