NCP6324

Buck Converter Synchronous 3 MHz, 2 A NCP6324, NCV6324 The NCP/NCV6324, a family of synchronous buck converters, which is optimized to supply different sub systems of portable applications powered by one cell Li−ion or three cell Alkaline/NiCd/ NiMH 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 NCP/NCV6324 is in a space saving, low profile 2.0 x 2.0 x 0.75 mm WDFN8 package or a WDFNW8 wettable flank package. Features 2.5 V to 5.5 V Input Voltage Range External Adjustable Voltage Up to 2 A Output Current 3 MHz Switching Frequency Synchronous Rectification Automatic Power Save (NCx6324B) or External Mode Selection (NCx6324C) Enable Input Power Good Output Option (NCx6324B) Soft Start Over Current Protection Active Discharge When Disabled Thermal Shutdown Protection WDFN−8, 2 x 2 mm, 0.5 mm Pitch Package and WDFNW8, 2 x 2 mm, 0.5 mm Pitch Package with Wettable Flanks Maximum 0.8mm Height for Super Thin Applications NCV Prefix for Automotive and Other Applications Requiring Unique Site and Control Change Requirements; AEC−Q100 Qualified and PPAP Capable These Devices are Pb−Free, Halogen Free/BFR Free and are RoHS Complian...
