TDK Corporation has extended the TDK-Lambda brand CCG family with two new options for 1.5W to 10W isolated DC-DC converters

     TDK Corporation has announced the expansion of its TDK-Lambda brand CCG Series of isolated DC-DC converters with the introduction of two new options in the 1.5W to 10W range. One of the latest improvements is the optional dual panel coating that provides additional protection for demanding environments such as industrial and railway applications. In addition, a larger 40-piece tray size has been introduced, simplifying the placement process for surface-mount models.

     The CCG series has 144 voltage and current combinations and supports 3.3V, 5V, 12V and 15V outputs, as well as +/-12V and +/-15V dual configurations. Dual output models can also be reconfigured to provide a single 24V and 30V output. Designed to accommodate a wide range of power supplies, all models operate in a wide input voltage range from 4.5 to 18V, 9 to 36V, or 18 to 76V DC, making them compatible with 5V, 12V, 24V, and 48V DC power supplies. The 4:1 input range helps simplify inventory management and procurement processes by allowing a single part number to cover multiple nominal input voltages.

     The compact design of the series ensures efficient use of board space, with the 1.5W and 3W models measuring 15.7 x 10.4mm (length x width), while the 6W and 10W versions measure 19 x 12.4mm (length x W). Using a non-encapsulated plastic housing, the converter eliminates potential quality issues associated with silicone potting compounds during reflow soldering.

     For precise voltage regulation, the single-output model includes a fine-tuning function that allows adjustments from -5% to +10% of the nominal value, compensating for the voltage drop across the PCB. Standard features on all models include overcurrent protection and a remote on/off function, which can also be used to switch the converter to standby mode. This greatly reduces offload power consumption to below 0.1W, extending battery life in portable applications.

     The CCG series is designed to operate in an ambient temperature range from -40°C to +100°C (depending on the model), with convection or forced air cooling. The converter offers 1,500Vdc input/output isolation and is fully certified to the IEC/UL/CSA/EN 62368-1 safety standard. They also carry the CE and UKCA marks to comply with the low voltage and RoHS directives.

     The range is ideal for a variety of demanding applications, including rail rolling stock and trackside infrastructure, robotics, telecommunications, data systems, test and measurement equipment, harsh environment process control, broadcast systems and battery powered equipment.
