DC/DC isolated converters provide 9W from SIP-8 package

New Products |
By Graham Prophet

Models are available with 2:1 (TMR 9) or 4:1 (TMR 9WI) input ranges and cover nominal inputs of 12V, 24V and 48V DC. Single and dual output voltages of 3.3V to 24V DC are available within the range. The converters offer a 50% higher power density compared to conventional SIP converters and can reliably operate up to 60°C environment temperature at full load or up to 85°C with a 50% load de-rating. The packages are designed to give their switching transistor an extended dissipation surface. This, together with an extra thermo-conducting potting compound, allows heat to be efficiently transferred to the metal casing and dissipated to the environment. Features include 1500 VDC I/O-isolation voltage, external On/Off, short current protection and EMC according EN55022 class A.
