WE-MAPI
SMD Metal Alloy Power Inductor
Application Example:
In the figure below, a four channel DC-DC converter is implemented to supply power to smart phone/tablet processing block. Each channel is intended to supply power
accordingly to processor, System on Chip (SOC), RAM and I/O interface module where WE-MAPI is used as storage element in all converters. Due to its characteristics
mentioned above, WE-MAPI is a very suitable storage element for high performance applications such as smart phones, tablets and high efficient consumer electronics.
