Delphi Series V48SH, 1/16

Brick 100W

DC/DC Power Modules: 48V in, 5V, 17A out

The Delphi Series V48SH, 1/16

Brick, 48V input, single output, isolated

DC/DC converter, is the latest offering from a world leader in power

systems technology and manufacturing ― Delta Electronics, Inc. This

product family provides up to 100 watts of power or 40A of output current

(1.8V and below) in an industry standard 1/16

brick form factor (1.30” x

0.90”). The 5V provides up to 91.5% efficiency at full load. 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. All modules are protected from abnormal input/output voltage,

current, and temperature conditions. For lower power needs, but in a

similar small form factor, please check out Delta V36SE (50W), S48SP

(36W or 10A) and S36SE (17W or 5A) series standard DC/DC modules.

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 100 μF electrolytic capacitor (ESR < 0.7 Ω at 100 kHz) mounted close to the input of the module to improve the stability.
PAGE 7
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. Remote on/off can be controlled by an external switch between the on/off terminal and the Vi(-) terminal. The switch can be an open collector or open drain.
PAGE 8
FEATURES DESCRIPTIONS (CON.) When using remote sense and trim, the output voltage of the module is usually increased, which increases the power output of the module with the same output current. Max rated current is guaranteed at full output voltage remote sense range. Output Voltage Adjustment (TRIM) To increase or decrease the output voltage set point, connect 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 9
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.
