Delphi DNT04, Non-Isolated Point of Load

DC/DC Power Modules: 2.4~5.5Vin, 0.75~3.63Vo, 5A out

The Delphi Series DNT04, 2.4-5.5V 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 DNT04 series provides a programmable output

voltage from 0.75V to 3.63V using external resistors. This product family

is available in surface mount or SIP package and provides up to 5A of

output current in an industry standard footprint. 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.

The DNT04, 5A modules have excellent thermal performance and can

provide full output current at up to 85℃ ambient temperature with no

airflow.

FEATURES DESCRIPTIONS FEATURES DESCRIPTIONS (CON.) Remote On/Off Output Voltage Programming The DNT series power modules have an On/Off pin for remote On/Off operation. Both positive and negative On/Off logic options are available in the DNT series power modules. The output voltage of the DNT can be programmed to any voltage between 0.75Vdc and 3.63Vdc by connecting one resistor (shown as Rtrim in Figure 28) between the TRIM and GND pins of the module.

FEATURE DESCRIPTIONS (CON.) Table 1 provides Rtrim values required for some common output voltages, while Table 2 provides value of external voltage source, Vtrim, for the same common output voltages. By using a 1% tolerance trim resistor, set point tolerance of ±2% can be achieved as specified in the electrical specification.

THERMAL CONSIDERATIONS 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.
