5-ball WLCSP
Supported by ADIsimPowerв„ў design tool The ADP2109 is a high efficiency, low quiescent current stepdown dc-to-dc converter with an internal discharge switch that
allows automatic discharge of the output capacitor in an ultrasmall 5-ball WLCSP package.
The total solution requires only three tiny external components. …
