Overview
The NCP6324CMTAATBG, produced by onsemi, is a synchronous buck converter optimized for supplying different subsystems in portable applications powered by one-cell Li-ion or three-cell Alkaline/NiCd/NiMH batteries. This device is part of the NCP/NCV6324 family, which offers high efficiency and compact design. It operates at a 3 MHz switching frequency, allowing the use of small inductors and capacitors, and features input supply voltage feedforward control to handle a wide input voltage range. The NCP6324CMTAATBG is available in a space-saving, low-profile WDFN8 package.
