| IC revision | 1.0 |
Description
Image sensor evaluation board.Synchronous Buck Converter, 3 MHz, 2 AThe NCP6324B/C, a family of synchronous buckconverters, which is optimized to supply different subsystems of portable applications powered by one cell Li-ionor three cell Alkaline/NiCd/NiMH batteries. The devices areable to deliver up to 2 A on an external adjustable voltagerange from 0.6 V to 3.3 V. Operation with 3 MHz switchingfrequency allows employing small size inductor andcapacitors. Input supply voltage feed-forward control isemployed to deal with wide input voltage range.Synchronous rectification and automatic PWM/PFM powersave mode offer improved system efficiency. TheNCP6324B is in a space saving, low profile2.0 × 2.0 × 0.75 mm WDFN−8 package.
