GENERAL DESCRIPTION
Seriesof DC/DC converters offer watts power isolated outputs radiation tolerant design. outputs used positive outputs, positive negative output negative output with watts available from each output. Additionally outputs connected share load providing output with watts available output power. converters supply full power over temperature range 55°C +125°C. input voltage range volts offers system design engineers increased design flexibility. profile package 0.40 inches high with footprint square inches. Series converters packaged hermetically sealed, seam welded, gold plated, steel cases. feature, current sharing. separate outputs combined produce single output voltage while doubling output power capacity. Series incorporates internal filter ensure MIL-STD-461C CE03 compliance along with additional output filtering that reduces output noise bandwidth MHz.
CONFIGURABLE OUTPUTS: 16.5 VDC, DUAL SINGLE
series converters' dual outputs configured positive outputs, negative outputs, positive negative output. Additionally, outputs "stacked" increased output power load. Output voltages trimmed down, with volt output trimmable volts. outputs trimmed maximum 10%.
CONVERTER DESIGN
Series dual DC/DC converters switching regulators that interleaved power paths forward mode. They operate constant switching frequency kHz. They synchronized system clocks over frequency range MHz. Separate, isolated control loops each output achieve tight regulation over wide range load combinations. current-mode control design improves transient response introduces
Series DC/DC converters provide following features: Output voltage trim Fixed frequency operation Synchronization units system clock each other Primary current mode control Current sharing compatible inhibit Soft-start stress power-up
