Occupying 0.3 in.² of board space, TMR 9 and TMR 9WI Series provide 2:1 and 4:1 input range, respectively, with single and dual regulated output voltages. Units feature flat switching transistor with extended dissipation surface. Combined with extra thermo-conducting potting compound, heat losses can be transferred to metal casing and dissipated to environment. Operating from -40 to +60°C at full load, converters provide 1,500 Vdc I/O-isolation, external On/Off, and short current protection.
