TDK Corporation announces the introduction of 1.5 and 3W models to the TDK-Lambda CCG series of DC-DC converters which are capable of providing full load in ambient temperatures from -40 to +85°C with convection cooling. In addition to battery powered equipment, applications include process control, data communications, telecommunications and test or measurement-related products.
The CCG1R5 (1.5W) and CCG3 (3W) series is available with output voltages of 3.3, 5, 12, 15, ±12 or ±15 and the dual output versions can also be connected to provide a single 24 or 30V supply. All voltages and output power combinations can operate from either a 4.5 to 18V, 9 to 36V or 18 to 76Vdc input.
Single output models can be adjusted using the trim terminal over a -5% to +10% range for non-standard voltages. All models are protected against an over-current condition and the output can be inhibited using the remote on/off function. The input to output isolation voltage is 1,500Vdc.
The CCG1R5 and CCG3 converters share a common plastic case and measure 15.7mm (length) x 10.4mm (width) x 11.5mm (height). A choice of through-hole or surface-mount terminations is available in both power levels. On the highly automated production line utilising X-ray inspection, no encapsulation is used in order to avoid quality risks associated with silicone potting compounds during the customer reflow soldering process.
The full temperature range is -40 to +100°C, with derating above 85°C. Safety certification includes IEC/UL/CSA/EN 62368-1 with CE and UKCA marks to the Low Voltage and RoHS Directives.
