Delphi DNL, Non-Isolated Point of Load

DC/DC Power Modules: 2.8-5.5Vin, 0.75-3.63V/16A out

The Delphi Series DNL, 2.8-5.5V input, single output, non-isolated Point of

Load DC/DC converters are the latest offering from a world leader in power

system and technology and manufacturing -- Delta Electronics, Inc. The

DNL series provides a programmable output voltage from 0.75V to 3.63V

using an external resistor. The DNL converters have flexible and

programmable tracking and sequencing features to enable a variety of

startup voltages as well as sequencing and tracking between power

modules. This product family is available in a surface mount or SIP

package and provides 16A of current in an industry standard footprint. With

creative design technology and optimization of component placement,

these converters possess outstanding electrical and thermal performance

and extremely high reliability under highly stressful operating conditions.

TEST CONFIGURATIONS DESIGN CONSIDERATIONS Input Source Impedance L VI(+) 2 100uF Tantalum BATTERY VI(-) Note: Input reflected-ripple current is measured with a simulated source inductance. Current is measured at the input of the module. Figure 29: Input reflected-ripple test setup To maintain low noise and ripple at the input voltage, it is critical to use low ESR capacitors at the input to the module.
PAGE 9
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.

FEATURES DESCRIPTIONS (CON.) Vtrim  0.7  0.1698  Vo  0.7525 Over-Temperature Protection For example, to program the output voltage of a DNL module to 3.3 Vdc, Vtrim is calculated as follows 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.
PAGE 11
FEATURE DESCRIPTIONS (CON.) 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).
PAGE 12
FEATURE DESCRIPTIONS (CON.) Ratio-Metric Sequential Start-up Sequential start-up (Figure 40) is implemented by placing an On/Off control circuit between VoPS1 and the On/Off pin of PS2. Ratio–metric (Figure 42) is implemented by placing the voltage divider on the TRACK pin that comprises R1 and R2, to create a proportional voltage with VoPS1 to the Track pin of PS2. For Ratio-Metric applications that need the outputs of PS1 and PS2 reach the regulation set point at the same time.

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.
