TEST CONFIGURATIONS DESIGN CONSIDERATIONS Input Source Impedance To maintain low noise and ripple at the input voltage, it is critical to use low ESR capacitors at the input to the module. A highly inductive source 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.

Both positive and negative requirements of the end-use safety agency standards. On/Off logic options are available in the DCM series power modules.

Vo Remote Sense RLoad TRIM Rtrim The DCM provide Vo remote sensing to achieve proper GND 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 0.5V of loss. The remote sense line impedance shall be < 10.

FEATURE DESCRIPTIONS (CON.) When an analog voltage is applied to the SEQ pin, the output voltage tracks this voltage until the output reaches Voltage Margining the set-point voltage. The final value of the SEQ voltage Output voltage margining can be implemented in the DCM 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, Rmargin-down, from the Trim pin to the output pin for margining-down.

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.
