MARKING

The NCV6334B, a family of synchronous buck converters, which is

optimized to supply different sub systems of portable applications

batteries. The devices are able to deliver up to 2 A on an external

adjustable voltage. Operation with 3 MHz switching frequency allows

employing small size inductor and capacitors. Input supply voltage

feedforward control is employed to deal with wide input voltage

range. Synchronous rectification and automatic PWM/PFM power

save mode offer improved system efficiency. The NCV6334B is in a

space saving, low profile 2.0 x 2.0 x 0.75 mm WDFN−8 package.
