孤立的，高可靠性 Isolated, High Reliability
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.
