Delphi Series H48SR, 200W Half Brick Family
DC/DC Power Modules: 48V in, 1.8V/80A out
The Delphi Series H48SR Half Brick, 48V input, adjustable single
output, isolated, open frame DC/DC converters are the latest offering
from a world leader in power systems technology and manufacturing —
Delta Electronics, Inc. This product family provides up to 200 watts of
power or up to 80A of output current in an industry standard footprint.
This product represents the next generation of design technology which
may be utilized to provide high levels of current at very low output
voltages required by today's leading-edge circuitry. Utilizing an
advanced patented thermal and electrical design technology, the Delphi
Series H48SR converters are capable of providing much higher output
current capability with excellent transient response and lower common
mode noise. Featuring a wide operating output voltage range and high
current at low output voltages, these units offer more useable power
over a wide range of ambient operating conditions. The wide range
trimmable output feature allows the user to both reduce and
standardize part numbers across different and/or migrating voltage
requirements.

Page 8: 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 9: 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 (hiccup mode). The modules will try to restart after shutdown. - Page 10 FEATURES DESCRIPTIONS (CON.) Output Voltage Adjustment (TRIM) 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 SENSE(+) or SENSE(-). The TRIM pin should be left open if this feature is not used.

Page 11: 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. -
