Delphi D12S05020 Non-Isolated Point of Load

DC/DC Modules: 4.5V~13.2Vin, 0.59V~5.0Vout, 20A

The Delphi D12S05020 Series, 4.5V to 13.2V wide input, wide trim,

single output, non-isolated point of load (POL) DC/DC converters are

the latest offering from a world leader in power systems technology

and manufacturing — Delta Electronics, Inc. The D12S05020

product family is part of the second generation, non-isolated

point-of-load DC/DC power modules for the data communication

applications which cut the module size by almost 50% in most of the

cases compared to the first generation NC series POL modules. The

D12S05020 product family provides an ultra wide input range to

support 5V, 8V, 9.6V, and 12V bus voltage point-of-load applications

and it offers 20A of output current in a vertically mounted through-hole

miniature package and the output can be resistor trimmed from

0.59Vdc to 5.0Vdc. It provides a very cost effective, high efficiency,

and high density 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.

DESIGN CONSIDERATIONS FEATURES DESCRIPTIONS The D12S05020 series uses a single phase and voltage mode controlled buck topology. The output can be adjusted in the range of 0.59Vdc to 5.0Vdc by a resistor from Trim pin to ground. Enable (On/Off) The converter can be turned ON/OFF by remote control with positive on/off (ENABLE pin) logic. The converter DC output is disabled when the signal is driven low (below 0.8V).

FEATURES DESCRIPTIONS (CON.) Over-Current and Short-Circuit Protection Output Voltage Programming The D12S05020-1 series modules have non-latching over-current and short-circuit protection circuitry. When over current condition occurs, the module goes into the non-latching hiccup mode. When the over-current condition is removed, the module will resume normal operation.

THERMAL CONSIDERATION THERMAL CURVES Thermal management is an important part of the system design. To ensure proper, reliable operation, sufficient cooling of the power module is needed over the entire temperature range of the module. Convection cooling is usually the dominant mode of heat transfer. Hence, the choice of equipment to characterize the thermal performance of the power module is a wind tunnel.
