Delphi DNL, Non-Isolated Point of Load

DC/DC Power Modules: 8.3-14Vin, 0.75-5.0V/16A out

The Delphi series DNL, 8.3~14V 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 DNL series provides a programmable output voltage from 0.75V to

5.0V through an external trimming resistor. The DNL converters have

flexible and programmable tracking and sequencing features to enable a

variety of sequencing and tracking between several point of load power

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

package and provides up to 16A of output current in an industry standard

footprint and pinout. 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 TO OSCILLOSCOPE 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 17: 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 7
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.
PAGE 8
FEATURES DESCRIPTIONS (CON.) 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.

FEATURE DESCRIPTIONS (CON.) Table 1 provides Rtrim values required for some common output voltages, while Table 2 provides values 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.

FEATURE DESCRIPTIONS (CON.) The output voltage tracking feature (Figure 27 to Figure 29) is achieved according to the different external connections. If the tracking feature is not used, the TRACK pin of the module can be left unconnected or tied to Vin. Sequential Start-up Sequential start-up (Figure 27) is implemented by placing an On/Off control circuit between VoPS1 and the On/Off pin of PS2.
PAGE 11
FEATURE DESCRIPTIONS (CON.) THERMAL CONSIDERATIONS Ratio-Metric 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.
