Packaged in 1" x 2" encapsulated modules, the TWR 22W series DC/DC converters
offer three outputs arranged as a unipolar low voltage supply and a higher voltage
bipolar output pair. The unipolar section supplies either +3.3V at 4A maximum or
+5V at 3A maximum. The bipolar outputs are either ±12Vdc at 300mA maximum or
±15Vdc at 250mA and are ideal for op amps, linear or analog circuits. A single TWR
converter can power applications with combined analog and digital circuits such as a
CPU-controlled voice switch, embedded telephone modem or analytical instruments.
The input section is fully isolated from the outputs up to 1500Vdc minimum using
Basic insulation. Three wide input ranges are available including 10-18V (12Vdc
nominal), 18-36V (24Vdc nomimal) or 36-75V (48Vdc nominal). Peak-to-peak
output ripple/noise is typically 80-100mV at full load. Efciencies range up to 87%.
The TWR 22W series outputs will limit their current if driven to overload and may
be short circuited indenitely without damage. The inputs will shut down if input voltage
is either over or under limits or has reversed input voltage. These converters will
operate up to +65°C with no derating or at higher temperatures with adequate airow.
The unipolar output features line and load regulation of ±1%. Excellent dynamic
response assures transient load change settling within 100 microseconds. Other
convenience features include a remote On/Off control to turn the outputs on via
digital logic, CPU bit, control transistor or a relay.
Fabrication uses DATEL’s advanced surface mount automated pick-and-place
assembly and computer-controlled parameter testing. All TWR 22W series are
designed to meet safety requirements in UL, EN60950 and CSA-C22.2 No.234.
