D12S05030-2 Non-Isolated Point of Load
DC/DC Power Modules:
10.8~13.2Vin, 0.9V-3.3V, 40A & 5.1V, 30A out
The D12S05030-2 series, 10.8~13.2V input, single output, non-isolated
point of load DC/DC converters are the latest offering from a world leader in
power systems technology and manufacturing -- Delta Electronics, Inc. The
D12S05030-2 series product provides up to 40A (3.3V and below) and the
output can be resistor trimmed from 0.9Vdc to 5.1Vdc. It provides a very
cost effective point of load solution. With creative design technology and
optimization of component placement, these converters possess
outstanding electrical and thermal performance, as well as extremely high
reliability under highly stressful operating conditions.
