Delphi D12S300-1 Non-Isolated Point of Load

DC/DC Modules: 4.5V~13.8Vin, 0.6V~5.0Vout, 60A

The D12S300-1 series, 4.5~13.8V 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 D12S300-1 series product provides up to 60A and

the output can be resistor trimmed from 0.6Vdc to 5.0Vdc. 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.

The D12S300-1 series is a voltage mode controlled Buck topology. The

output can be trimmed in the range of 0.6Vdc to 5.0Vdc by an external

resistor from Trim pin to Ground. 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. When

this pin is floating the module will turn on. The converter can protect

itself by entering hiccup mode against over current and short circuit

condition. Also, the converter will shut down when an over voltage

protection is detected.

DESIGN CONSIDERATIONS FEATURES DESCRIPTIONS The D12S300-1 uses a three phase and voltage mode controlled buck topology. The output can be trimmed in the range of 0.6Vdc to 5.0Vdc by a resistor from Trim pin to Ground. Enable (On/Off) The converter can be turned ON/OFF by remote control. Positive on/off (ENABLE pin) logic implies that the converter DC output is enabled when the signal is driven high (greater than 1.2V) or floating and disabled when the signal is driven low (below 0.7V).

FEATURES DESCRIPTIONS (CON.) Input Under-Voltage Lockout Output Voltage Programming The input under-voltage lockout prevents the converter from being damaged while operating when the input voltage is too low. The lockout occurs between 4.1V to 4.5V. The output voltage of the NE series is trimmable by connecting an external resistor between the trim pin and output ground as shown Figure 28 and the typical trim resistor values are shown in Table 1.
PAGE 9
FEATURES DESCRIPTIONS (CON.) Voltage Margining Adjustment Output voltage margin adjusting can be implemented in the ND modules by connecting a resistor, Rmargin-up, from the Trim pin to the Ground for margining up the output voltage. Also, the output voltage can be adjusted lower by connecting a resistor, Rmargin-down, from the Trim pin to the voltage source Vt. Figure 29 shows the circuit configuration for output voltage margining adjustment.

THERMAL CONSIDERATION THERMAL CURVES (D12S300-1) 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.
