Delphi Series S48SP, 35W 1x1 Brick
DC/DC Power Modules: 48V in, 5V/7A out
The Delphi Series S48SP, 1x1 Brick, 48V input, single output, isolated
DC/DC converters are the latest offering from a world leader in power
systems technology and manufacturing -- Delta Electronics, Inc. This
product family is available in a surface mount or through-hole package
and provides up to 35 watts of power or 10A of output current (3.3V and
below) in a new 1x1 form factor (1.3"x0.96"x0.33"). The pinout is
compatible with the industry standard 1x2 products. 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. Typical efficiency of the 5V/7A module is 90%. All modules
are fully protected against abnormal input/output voltage, current, and
temperature conditions.

Page 7: Design Considerations
DESIGN CONSIDERATIONS Input Source Impedance The impedance of the input source connecting to the DC/DC power modules will interact with the modules and affect the stability. A low ac-impedance input source is recommended. If the source inductance is more than a few μH, we advise adding a 10 to 100 μF electrolytic capacitor (ESR <... -
Page 8: Features Descriptions
FEATURES DESCRIPTIONS Over-Current Protection The modules include an internal output over-current protection circuit, which will endure current limiting for an unlimited duration during output overload. If the output current exceeds the OCP set point, the modules will automatically shut down, and enter hiccup mode or latch mode, which is optional. - Page 9 FEATURES DESCRIPTIONS (CON.) Output Voltage Adjustment To increase or decrease the output voltage set point, the modules may be connected with an external resistor between the TRIM pin and either the Vo(+) or Vo(-). The TRIM pin should be left open if this feature is not used.

Page 10: Thermal Considerations
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. - Page 11 PICK AND PLACE LOCATION SURFACE-MOUNT TAPE & REEL RECOMMENDED PAD LAYOUT (SMD) DS_S48SP05007_05222008...
