NCP6334B, NCP6334C
3MHz, 2A Synchronous
Buck Converter
High Efficiency, Low Ripple, Adjustable
Output Voltage
The NCP6334B/C, a family of synchronous buck converters, which
is optimized to supply different sub systems of portable applications
powered by one cell Liâion 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 2.0 x 2.0 x 0.75 mm WDFNâ8 package.
