SynQor has announced the release of a range of isolated Quarter Brick DC/DC converters to address industrial, medical and telecom applications running from a 12V and/or 24V bus (operating range is 9-36V). Single output voltages offered range from 1.8V to 48V (with nine different models available), and are capable of supplying up to 40A or 100W of usable power.

Housed in the industry standard 2.30 x 1.45in Quarter Brick footprint and pinout, the IQ18xxxQTAxx family of devices are available as open frame units for convection-cooled applications; with baseplates for conduction-cooled applications; and for the first time, fully encapsulated for harsh environment applications.

Utilizing SynQor’s well proven Synchronous Rectified Topology, efficiencies of up to 91% are achieved in the following configurations: 1.8V/40A; 3.3V/30A; 5V/20A; 7V/14A; 12V/8A; 15V/7A; 24V/4A; 30V/3A and 48V/2A. The modules have at least a basic-grade isolation rating between input and output of 2250Vdc (reinforced-grade for the encapsulated version). Calculated MTBF figures are in excess of 2MHrs, and all units are fully 6/6 RoHS compliant.

Control and protection features include remote sense, a wide output voltage trim range of -20% to +10%, input under-voltage lockout, output OVP, current limit, short circuit protection, and thermal shutdown. Operating temperature range is -40 to +100degC.

Sample and production quantities are available immediately with a stock to 12-week lead-time. The modules are priced at $103 in OEM quantities.
