3 MHz, 2 A Fixed-Frequency Synchronous Buck Converter
High Efficiency, Low Ripple, Adjustable Output Voltage
NCP6354
The NCP6354, a synchronous buck converter, which is optimized to supply the different sub systems of portable applications powered by one cell Li−ion or three cell Alkaline/NiCd/NiMH batteries. The device is 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 offers improved system efficiency. The NCP6354 is in a space saving, low profile 2.0x2.0x0.75 mm WDFN−8 package.
Features
• 2.3 V to 5.
