Delphi D12S300-1 D/E Non-Isolated Point of

Load DC/DC Modules: 4.5V~13.8Vin, 0.6V~5Vout,

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 5Vdc. 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 5Vdc 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

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 5Vdc by a resistor from Trim pin to Ground.

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). Negative on/off logic is optional.

The converter provides an open collector Power Good signal. The power good signal is pulled low when output is not within ±10% of Vout or Enable is OFF.

The converter can protect itself by entering hiccup mode against over current and short circuit condition.

Safety Considerations

It is recommended that the user to provide a fuse in the input line for safety. The output voltage set-point and the output current in the application could define the amperage rating of the fuse.

FEATURES DESCRIPTIONS

Enable (On/Off)

The ENABLE (on/off) input allows external circuitry to put the D12S300-1 converter into a low power dissipation (sleep) mode. Positive ENABLE is available as standard.

Positive ENABLE units of the D12S300-1 series are turned on if the ENABLE pin is high or floating. Pulling the pin low will turn off the unit. With the active high function, the output is guaranteed to turn on if the

ENABLE pin is driven above 1.2V. The output will turn off if the ENABLE pin voltage is pulled below 0.7V.

The ENABLE input can be driven in a variety of ways as shown in Figures 25 and 26. If the ENABLE signal comes from the primary side of the circuit, the ENABLE can be driven through either a bipolar signal transistor

(Figure 25). If the enable signal comes from the secondary side, then an opto-coupler or other isolation devices must be used to bring the signal across the voltage isolation (please see Figure 26).

FEATURES DESCRIPTIONS (CON.)

Input Under-Voltage Lockout

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.

Over-Current and Short-Circuit Protection

The D12S300-1 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.

An over current condition is detected by measuring the voltage drop across the inductor. The voltage drop across the inductor is also a function of the inductor ’s DCR.

Note that none of the module specifications are guaranteed when the unit is operated in an over-current condition.

Remote Sense

The D12S300-1 provides Vo remote sensing to achieve proper regulation at the load points and reduce effects of distribution losses on output line. In the event of an open remote sense line, the module shall maintain local sense regulation through an internal resistor. The module shall correct for a total of 0.6V of loss. The remote sense connects as shown in Figures 27.

Figure 27 : Circuit configuration for remote sense

DS_D12S300-1_12242014

Output Voltage Programming

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.

Power Good

The converter provides an open collector signal called Power

Good. This output pin uses positive logic and is open collector. This power good output is able to sink 5mA and set high when the output is within ±10% of output set point. The power good signal is pulled low when output is not within

±10% of Vout or Enable is OFF.

FEATURES DESCRIPTIONS (CON.)

Current Sharing (optional)

The parallel operation of multiple converters is available with the D12S300-1 E. The converters will current share to be within +/- 10% of each other. In additional to connect the I-Share pin together for the current sharing operation, the remote sense lines of the paralleled units must be connected at the same point for proper operation. Also, units should be turned on/off by enable at the same time. Hot plugging is not recommended. The current sharing diagram show in figure 29.

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 30 shows the circuit configuration for output voltage margining adjustment.

Output Capacitance

There are internal output capacitors on the D12S300-1 series modules. Hence, no external output capacitor is required for stable operation.

THERMAL CONSIDERATION

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.

Thermal Testing Setup

Delta’s DC/DC power modules are characterized in heated vertical wind tunnels that simulate the thermal environments encountered in most electronics equipment. This type of equipment commonly uses vertically mounted circuit cards in cabinet racks in which the power modules are mounted.

The following figure shows the wind tunnel characterization setup. The power module is mounted on a test PWB and is vertically positioned within the wind tunnel. The space between the neighboring PWB and the top of the power module is constantly kept at

6.35mm (0.25’’).

Thermal Derating

Heat can be removed by increasing airflow over the module. To enhance system reliability, the power module should always be operated below the maximum operating temperature. If the temperature exceeds the maximum module temperature, reliability of the unit may be affected.
