Standard, ES, or 883 (Class H). DESCRIPTION The MSA Series™ of high frequency DC/DC converters offers a new standard of performance for low power, military/aerospace grade DC/DC converters. MSA parts provide up to 5 watts output power over the full military temperature range with up to 76% efficiency. Thick-film hybrid techniques provide military/aerospace reliability levels and optimum miniaturization. The hermetically sealed case is only 1.075 by 1.075 inches — with a height of only 0.270 inches. Power density for the MSA Series parts is 16 watts per cubic inch. www.DataSheet4U.com The MSA WIDE VOLTAGE RANGE The MSA converters are designed to provide full power operation over a full 16 to 40 VDC voltage range. Operation below 16 volts, including MIL-STD-704E emergency power conditions is possible with derated power. Please refer to the low line dropout graphs (Figures 17 and 18) for details. A low voltage lockout feature keeps the converter shutdow...
