NCP6332B

3 MHz, 1.2 A Synchronous Buck Converter High Efficiency, Low Ripple, Adjustable Output Voltage NCP6332B, NCP6332C The NCP6332B/C, 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 1.2 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 NCP6332B/C is in a space saving, low profile 2.0 x 2.0 x 0.75 mm WDFN−8 package. Features 2.3 V to 5.5 V Input Voltage Range External Adjustable Voltage Up to 1.2 A Output Current 3 MHz Switching Frequency Synchronous Rectification Automatic Power Save (NCP6332B) or External Mode Selection (NCP6332C) Enable Input Power Good Output Option (NCP6332B) Soft Start Over Current Protection Active Discharge When Disabled Thermal Shutdown Protection WDFN−8, 2 x 2 mm, 0.5 mm Pitch Package Maximum 0.8mm Height for Super Thin Applications This is a Pb−Free Device Typical Applications Cellular Phones, Smart Phones, and PDAs Portable Media Players Digital Still Cameras Wireless and DSL Modems USB Powered Devices Point of Load Game and Entertainment System www.onsemi.com MA...
