Portable applications such as smartphones, tablet PCs, ebooks and MP3 players provide ever increasing functionality and a richer user experience in wider but slimmer form factors.
As their functionality increases, battery operating time is a critical factor in the design of these portable devices. The board size must be kept to a minimum while increasing the level of efficiency in power management. One way of reducing power consumption is to turn off applications when they are not being used. This mechanism uses MOSFETs as load switches. The other way is to reduce the operating voltage of the major components in the application.
Panasonic’s new low threshold CSP MOSFET series reduces conduction losses and the operating voltage that together translate into lower power consumption and dissipation without affecting the performance.
The new Low Threshold CSP MOSFET series come in 3 different sizes with both polarities.
