Delphi Series V36SE, 1/16

Brick

DC/DC Power Modules: 18~75Vin, up

to 50W

The Delphi Series V36SE, 1/16

Brick, 18~75V wide

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 50 watts of power in the

industry standard 1/16

brick form factor (1.30”x0.90”)

and pinout. 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. For the 12V output module, it

delivers 50W (4.2A) output with 36 to 75V input and

delivers 40W (3.5A) output while the input is 18 to 36V to

the same module. Typical efficiency of the 12V/4.2A

module is greater than 88%. 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 S48SP

(36W or 10A) and S36SE (17W or 5A) series standard

DC/DC modules.

OPTIONS

 SMD pins

 Positive remote On/Off

 OTP and output OVP, OCP mode

(Auto-restart or latch)

APPLICATIONS

 Optical Transport

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
When installed into a Class II equipment (without grounding), spacing consideration should be given to the end-use installation, as the spacing between the module and mounting surface have not been evaluated. The power module has extra-low voltage (ELV) outputs when all inputs are ELV. This power module is not internally fused. To achieve optimum safety and system protection, an input line fuse is highly recommended.
PAGE 8
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. For hiccup mode, the module will try to restart after shutdown. If the over current condition still exists, the module will shut down again.
PAGE 9
FEATURES DESCRIPTIONS (CON.) If the remote sense feature is not used to regulate the output at the point of load, please connect SENSE(+) to Vo(+) and SENSE(–) to Vo(–) at the module. The output voltage can be increased by both the remote sense and the trim; however, the maximum increase is the larger of either the remote sense or the trim, not the sum of both.
PAGE 10
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.
