Delphi Series V48SR, 1/16

Brick 65W

The Delphi Series V48SR, 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 66 watts of power or 25A of output

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

brick form factor

(1.30” x 0.90”). The 5.0V output offers one of the highest output currents

available and provides up to 91.0% 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 with the

5.0V output, but in a similar small form factor, please check out Delta

S48SP (36W or 5V/7A) and S48SE (17W or 5V/3A) series standard

DC/DC modules.

Safety 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 < 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. Care should be taken to ensure that the maximum output power does not exceed the maximum rated power. 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(-).
PAGE 9
THERMAL CONSIDERATIONS Thermal Derating 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. Heat can be removed by increasing airflow over the module. To enhance system reliability, the power module should always be operated below the maximum operating temperature.
