A series of non-isolated point of load (POL) dc-dc converters from FDK feature up to 39 W of output power. The converters deliver up to 6 Amperes (A) of output current at power densities up to 860 Watts/cubic inch in an SMD package, and up to 4 A of output current at power densities up to 760 Watts/cubic inch in an SIP package. They have efficiencies up to 93%. Operating temperature is up to 85 degrees Celsius in the SMD package, and up to 70 degrees Celsius in the SIP package. The converters operate from a 5.6 Vdc to 14.0 Vdc input, and output from 0.8 Vdc to 6.6 Vdc. From $4.60 in 1,000 piece quantities.
