NCP6334B

Overview
3 MHz, 2 A Synchronous Buck Converter High Efficiency, Low Ripple, Adjustable Output Voltage NCP6334B, NCP6334C The NCP6334B/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 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 NCP6334B/C is in a space saving, low profile 2.
