2.42mm BGA Packages
n APPLICATIONS The LTM®4643 is a quad DC/DC step-down µModule
(power module) regulator with 3A per output. Outputs can
be paralleled in an array for up to 12A capability. Included
in the package are the switching controllers, power FETs,
inductors and support components. Operating over an
input voltage range of 4V to 20V or 2.375V to 20V with
an external bias supply, the LTM4643 supports an output …
