NCP6323

Buck Converter Synchronous 3 MHz, 2 A High Efficiency, Low Ripple, Adjustable Output Voltage NCP6323, NCV6323 The NCP/NCV6323 is a synchronous buck converter 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 offer improved system efficiency. The NCP/NCV6323 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 Enable Input Power Good Output Option Soft−Start Over Current Protection Active Discharge When Disabled Thermal Shutdown Protection WDFN8, 2 x 2 mm, 0.5 mm Pitch Package & WDFNW8, 2 x 2 mm, 0.5 mm Pitch Package with Wettable Flanks Maximum 0.8 mm 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 Compliant Typical Applications Cellular Phones, Smart Phones, and PDAs Portable Medi...
