DC/DC Power Converter Module (Missile Application)

This DC/DC Miniature Switch Mode Power Supply (MSPS) is designed for use in missile applications. The MSPS uses a +/-20Vdc input voltage to provide six regulated DC voltage outputs. These voltage outputs are –2500V, +640V, +180V, +15V, -15V and +5V. The DC/DC MSPS includes filtering on the input to reject high frequency noise spikes generated by mechanical power generators. The line and load regulation for the +640V output is less than 1%. The voltage regulation for the low voltage outputs is less than 4%. The power supply will operate from an input voltage range of 16Vdc to 35Vdc. The MSPS will reject 1-volt noise spikes generated at 1kHz. The power density of the MSPS is 5 Watts per cubic inch.
