Series: 3.0A DC/DC Converters 36-75V Input 1.5V, 1.8V, 2.5V, 3.3V 5.0V Outputs Typical Application
This series converters does require external components proper operation. However, distribution input voltage converter contains significant inductance, capacitor across input terminals required stabilize input voltage. minimum 1µF, quality electrolytic ceramic capacitor recommended this purpose. output decoupling recommend connecting ceramic capacitor directly across output pins converter.

Output Current Limiting
When output overloaded above maximum output current rating, voltage will start reduce maintain output power safe level. condition high overload short-circuit where output voltage pulled below approximately Vo.Nom, unit will enter `Hiccup' mode operation. Under this condition unit will attempt restart, approximately every 25ms until overload cleared.

Shutdown Feature
remote control functions normal soft shutdown. referenced -Vin pin. With positive logic, when remote control pulled low, output turned unit goes into very input power mode. open collector switch recommended control voltage between remote control -Vin converter. remote control pulled internally, external voltage source required. user should avoid connecting resistor between remote control +Vin pin. user must take care ensure that reference control connected close pin. control signal must referenced ahead filtering, remotely from unit. remote control used, left floating.
Thermal Considerations
converter designed natural forced convection cooling. output power converter limited maximum case temperature (Tc). ensure reliable long term operation converters, comply with safety agency requirements, Power-One limits maximum allowable case temperature (Tc) 100°C (see Mechanical Drawings).
Note: When output voltage trimmed output power from converter must exceed maximum rating. This determined measuring voltage output pins, multiplying output current.

Series: 3.0A DC/DC Converters 36-75V Input 1.5V, 1.8V, 2.5V, 3.3V 5.0V Outputs Safety Considerations
These converters feature 1500 Volt isolation from input output. input output resistance greater than 10MOhm. These converters provided with Operational Insulation between input output circuits according EN60950 UL1950 CSA60950-00. Nevertheless, system using converter needs receive safety agency approval, certain rules must followed design system. particular, creepage clearance requirements enduse safety requirements must observed. These documents include UL60950, CSA60950-00 EN60950, although specific applications have additional requirements. order output converter considered SELV (Safety Extra Voltage) TNV-1, according EN60950 UL1950 CSA60950-00, following requirements must system design: converter internal fuse. external fuse must provided protect system from catastrophic failure. fuse with rating greater than 2.0A recommended. user select lower rating fuse based upon inrush transient maximum input current converter, which occurs minimum input voltage. Both input traces chassis ground trace applicable) must capable conducting current times value fuse without opening. fuse must placed grounded input line, any. voltage source feeding module SELV, output converter considered SELV grounded ungrounded. circuitry converter generate transients, which exceed input voltage. Even input voltage SELV (<60V) components primary side converter have considered hazardous. safety interlock needed prevent user from accessing converter while operational.
