Integrated Point-of-Load Power Modules:
11V~36V input, 3.3~6.5V and 3A Output
The Delphi Series IPM24S0B0 non-isolated, fully integrated
Point-of-Load (POL) power modules, are the latest offerings from a
world leader in power systems technology and manufacturing --
output current or 20W of output power in an industry standard,
compact, IC-like, molded package. It is highly integrated and does
not require external components to provide the point-of-load
function. A copper pad on the back of the module; in close contact
with the internal heat dissipation components; provides excellent
thermal performance. The assembly process of the modules is fully
automated with no manual assembly involved. These converters
possess outstanding electrical and thermal performance, as well as
extremely high reliability under highly stressful operating conditions.
IPM24S0B0 operates from an 11V~36V source and provides a
programmable output voltage from 3.3V to 6.5V. The IPM product
family is available in both a SMD or SIP package. IPM24S family is
also available for output 1.2V~2.5V. Please refer to IPM240A0
datasheet for details.
