MODEL 830-004
Power Supply Module
DESCRIPTION
The 830-004 is a single output isolated DC/DC
converter with an input range of 110 to 375 Vdc. This
allows the module to operate from any rectified 80 to
265 Vac line, corresponding to line voltages found
worldwide. Fixed output voltages between 5 to 18 Vdc
are available to suit a variety of applications. Low cost,
high reliability and small dimensions are the main
characteristics of this design. The use of an advanced
PWM provides for stable and efficient operation over a
wide load range.
FEATURES
• Continuous 6 watts of output power without use of a heat sink
• Wide input voltage range from 110 Vdc to 375 Vdc
• Single fixed regulated output, voltages available from 5 Vdc to 18 Vdc
• Sustains continuous short circuit
• Two sided layout design and SIP package minimized board space requirement
• Efficient circuit design constructed on a thermally conductive ceramic substrate
• UL recognition pending
APPLICATIONS
• Provides DC power for PWM and control circuitry for off-line switching power suppliers
• Provides isolated low DC voltages from AC line voltage levels (rectifier external)
• Battery chargers for portable personal electronics
7
• Industrial controls and line monitoring
• Stand-alone power supply for small electronics and µP controlled appliances
• Replacement for wall mount transformers and linear regulators
Specifications subject to change without notice.

APPLICATION NOTES
Model 830-004 is a complete DC/DC module based on
a flyback circuit topology.
To operate from an AC line, a bridge rectifier must be
added. A DB104 bridge rectifier or four IN4005
configured as pictured.
Most applications require the addition of output
capacitance. The capacitor’s voltage rating should be
selected in correlation to the output voltage of the
830-004. Choose sufficient capacitance to reduce the
output ripple to an acceptable level for the application.
Diodes should be 600 volts, 1 amp and should be used
in conjunction with a 47µF input capacitor. Choose the
capacitor voltage rating appropriately. For example,
117 Vac generates 165 volts peak. At a 1.5 x derating,
use a 250 volt capacitor.
A 47µF electrolytic should generally be suitable and
should be located close to the output pins.
