NCP6324 Datasheet, PDF (1/14 Pages) ON Semiconductor – 3MHz, 2A Synchronous Buck Converter

NCP6324, NCV6324
3MHz, 2A Synchronous
Buck Converter
High Efficiency, Low Ripple, Adjustable
Output Voltage
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 WDFN−8 package.
