OB3677

GENERAL DESCRIPTION

OB3677 is a low system cost driver to remove/suppress the 100/120 Hz current ripple for LED lighting applications.

OB3677 integrates a NMOSFET and the output current is suggested less than 150mA.

OB3677 can be used in traditional and dimming LED lighting application.

OB3677 is offered in SOT-23-3 and SOT-89-3 package.
