DESCRIPTION
Interpoint's Seriesof DC/DC converters offer wide input voltage range choice nine different output voltage configurations comprised single, dual triple outputs. converters will withstand transients milliseconds while maintaining output voltages (with exception volt single dual outputs which will withstand transients volts volt single dual outputs which will withstand volts). Series operates full watts output power watts volt single output) over military temperature range -55°C +125°C while maintaining input output noise. When (0.8 applied inhibit terminal converter shuts down, typically drawing input current. Inhibit terminal resistance ohms draws typical.
SYNCHRONIZATION FUNCTION
Applying external signal duty cycle will synchronize converter your system requirements. Free clock frequency approximately kHz. used, sync terminal must left unconnected.
TRIM
Single output converters feature trim range high 110% Vout nominal, depending model. trim connect resistor from output common (pin trim terminal (pin trim down, connect resistor from positive output (pin trim terminal (pin Figure trim tables more information.
CONVERTER DESIGN
Series DC/DC converters switching regulators that continuous flyback conversion topology with clock frequency approximately kHz. Series converters incorporate internal converters with converter phase shifted 180° from other create dual phase/phase-shifted operation. Each internal converters operates approximately one-half clock frequency. This proprietary technology eliminates cross regulation, minimizes input ripple, greatly reduces output ripple improves efficiency. triple output models, this design provides completely independent regulation with cross regulation effect between main auxiliary outputs minimum loading required main output.
UNDERVOLTAGE LOCKOUT
undervoltage lockout approximately keeps system current levels during startup.
SHORT CIRCUIT PROTECTION
Under short circuit conditions 130% more full load current, converter will protect itself shutting down. Short circuit duration should brief because power dissipation cause internal temperatures rise rapidly. Restart automatic upon removal short circuit.
INHIBIT FUNCTION
Open collector levels control inhibit circuit. converter enabled when inhibit terminal left unconnected when inhibit terminal connected voltage between 11.5
