TEST CONFIGURATIONS

DESIGN CONSIDERATIONS

TO OSCILLOSCOPE

Input Source Impedance

L

VI(+)

To maintain low noise and ripple at the input voltage, it is

critical to use low ESR capacitors at the input to the

module. Figure 32 shows the input ripple voltage (mVp-p)

for various output models using 200 µF(2 x100uF) low

ESR tantalum capacitor (KEMET p/n: T491D107M016AS,

AVX p/n: TAJD107M106R, or equivalent) in parallel with

47 µF ceramic capacitor (TDK p/n:C5750X7R1C476M or

equivalent). Figure 33 shows much lower input voltage

ripple when input capacitance is increased to 400 µF (4 x

100 µF) tantalum capacitors in parallel with 94 µF (2 x 47

µF) ceramic capacitor.

DESIGN CONSIDERATIONS (CON.)

FEATURES DESCRIPTIONS

The power module should be connected to a low

ac-impedance input source. Highly inductive source

impedances can affect the stability of the module. An

input capacitance must be placed close to the modules

input pins to filter ripple current and ensure module

stability in the presence of inductive traces that supply

the input voltage to the module.

Remote On/Off

The DNM/DNL 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

DNM/DNL series power modules.

For positive logic module, connect an open collector

(NPN) transistor or open drain (N channel) MOSFET

between the On/Off pin and the GND pin (see figure 34).

Positive logic On/Off signal turns the module ON during

the logic high and turns the module OFF during the logic

low. When the positive On/Off function is not used, leave

the pin floating or tie to Vin (module will be On).

Safety Considerations

For safety-agency approval the power module must be

installed in compliance with the spacing and separation

requirements of the end-use safety agency standards.

For the converter output to be considered meeting the

requirements of safety extra-low voltage (SELV), the

input must meet SELV requirements. The power

module has extra-low voltage (ELV) outputs when all

inputs are ELV.

For negative logic module, the On/Off pin is pulled high

with an external pull-up resistor (see figure 35). Negative

logic On/Off signal turns the module OFF during logic

high and turns the module ON during logic low. If the

negative On/Off function is not used, leave the pin

floating or tie to GND. (module will be On)

The input to these units is to be provided with a

maximum 15A time-delay fuse in the ungrounded lead.

Over-Current Protection

To provide protection in an output over load fault

condition, the unit is equipped with internal over-current

protection. When the over-current protection is

triggered, the unit enters hiccup mode. The units

operate normally once the fault condition is removed.

Over-Temperature Protection

The over-temperature protection consists of circuitry that

provides protection from thermal damage. If the

temperature exceeds the over-temperature threshold the

module will shut down. The module will try to restart after

shutdown. If the over-temperature condition still exists

during restart, the module will shut down again. This

restart trial will continue until the temperature is within

Output Voltage Programming

The output voltage of the DNM/DNL can be programmed

to any voltage between 0.75Vdc and 3.3Vdc by

connecting one resistor (shown as Rtrim in Figure 37)

between the TRIM and GND pins of the module. Without

this external resistor, the output voltage of the module is

0.7525 Vdc. To calculate the value of the resistor Rtrim

for a particular output voltage Vo, please use the

FEATURE DESCRIPTIONS (CON.)

The DNL family has 3 different option codes for TRACK

function.

The amount of power delivered by the module is the

voltage at the output terminals multiplied by the output

current. When using the trim feature, the output voltage

of the module can be increased, which at the same

output current would increase the power output of the

module. Care should be taken to ensure that the

maximum output power of the module must not exceed

the maximum rated power (Vo.set x Io.max ≤ P max).

Option code A: the output voltage TRACK

characteristic can be achieved when

the output voltage of PS2 follows the

output voltage of PS1 on a volt-to-volt

basis. (Figure 41)

Option code B: No TRACK function

Option code C: Implementation of advanced power

tracking techniques is based on connecting the power

good signal or selecting proper value for external

resistor R1 (Figure 40 to Figure 43).

Voltage Margining

Output voltage margining can be implemented in the

DNL modules by connecting a resistor, R margin-up, from

the Trim pin to the ground pin for margining-up the

output voltage and by connecting a resistor, R^margin-down,

from the Trim pin to the output pin for margining-down.

Figure 39 shows the circuit configuration for output

voltage margining. If unused, leave the trim pin

unconnected. A calculation tool is available from the

evaluation procedure which computes the values of R

margin-up and Rmargin-down for a specific output voltage and

margin percentage.

Voltage Tracking

PS2

The DNM/DNL family was designed for applications that

have output voltage tracking requirements during

power-up and power-down. The devices have a TRACK

pin to implement three types of tracking method:

sequential, ratio-metric and simultaneous. TRACK

simplifies the task of supply voltage tracking in a power

system by enabling modules to track each other, or any

external voltage, during power-up and power-down.

Ratio–metric is implemented by selecting the resistor

values of the voltage divider on the TRACK pin. To simplify

tracking method. The circuit diagram of Ratio-Metric is the

Sequential start-up (Figure 40) is implemented by

connecting the power good pin of PS1 to the TRACK pin

of PS2 with a resistor–capacitor (RC) circuit. Suggest to

use 1µF ceramic capacitor and 2KΩ resistor here.

Besides, this configuration requires PS1 to have a power

good function.

Simultaneous tracking (Figure 41) is implemented by

For type A (DNX0A0XXXX A), the simultaneous tracking

THERMAL CONSIDERATIONS

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 height of this fan duct is constantly kept

at 25.4mm (1’’).

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.
