IN Brief:
- CCG60 provides 60W output in the same one-inch-square footprint as the 30W CCG30.
- Input options cover 9–36V and 18–76V, with nominal outputs between 3.3V and 24V.
- Maximum efficiency reaches 93%, with shielding, functional insulation, and temperature-dependent output derating.
TDK-Lambda has expanded its CCG series with the CCG60 isolated DC-DC converter, providing up to 60W of output power within the same one-inch-square PCB footprint used by the 30W CCG30.
The converter measures 25.4 × 25.4mm, stands 13mm high, and weighs approximately 30g. Increasing output capacity without expanding the mounting area gives equipment designers another option where board space is constrained, although the higher power rating introduces additional thermal considerations.
Two versions provide 4:1 input voltage ranges. CCG60-24 models operate from 9V to 36V DC, while CCG60-48 versions accept 18V to 76V DC, covering different industrial and communications power distribution arrangements.
Both input families are available with nominal outputs of 3.3V, 5V, 12V, 15V, or 24V. This allows the same mechanical design to support different regulated supply rails without requiring a larger converter footprint.
The CCG60 achieves maximum efficiency of 93%, according to TDK-Lambda. Efficiency varies with the selected model and its operating conditions, including input voltage, output voltage, and load, so the headline figure should not be applied to every configuration.
Conversion losses are an important constraint in physically compact power electronics. Electrical energy not delivered to the output is dissipated primarily as heat, raising the converter’s internal temperature and affecting the surrounding components.
With a larger power rating in the same mounting area, removing that heat becomes especially important. The thermal behaviour depends on the converter’s construction, the PCB, airflow, enclosure design, and the ambient temperature in which the equipment operates.
TDK-Lambda specifies operation from −40°C to +85°C, with temperature-dependent output derating. Under the manufacturer’s stated conditions, the converter can supply 60W at an ambient temperature of 60°C, reducing to 30W at 85°C.
The CCG60 supports natural convection and forced-air cooling, but these methods provide different operating conditions. A system that has little airflow or is installed within a densely populated enclosure must be evaluated against its own temperature profile.
Thermal derating is particularly relevant when an industrial controller or communications device operates continuously. The required supply rail must remain available at the highest expected ambient temperature, not simply under nominal laboratory conditions.
The converter incorporates six-sided metal shielding intended to limit electromagnetic interference generated by its switching circuitry. Isolated DC-DC conversion uses rapidly changing voltages and currents, which can produce both conducted and radiated disturbances.
Shielding can help contain some of the associated electromagnetic fields, while the surrounding PCB layout and filtering components influence how interference propagates through the power system. The finished equipment’s EMC performance must still be established through appropriate measurement and testing.
Electrical isolation is provided between the input and output circuits. TDK-Lambda specifies an input-to-output withstand voltage of 1,500V DC for one minute and withstand ratings of 1,000V DC between the input or output circuitry and the case.
These ratings describe the converter’s functional insulation characteristics. They should not be interpreted as proof that the module alone satisfies every reinforced insulation or application-specific safety requirement.
Control functions include remote on/off operation and output voltage adjustment, allowing the converter to be incorporated into systems requiring coordinated power sequencing or a regulated output tailored to the connected load.
Overcurrent protection is also included to manage abnormal electrical loading. Protection behaviour must be considered with the characteristics of the connected circuit, particularly where several downstream loads are supplied from one converter.
The CCG60 is intended for industrial electronics, test and measurement equipment, communications systems, and broadcast applications. Such equipment can require several isolated supply rails within tightly constrained assemblies.
A nominal 24V industrial distribution system can use the CCG60-24 input family, while equipment built around a nominal 48V bus can use the CCG60-48. Both families include output voltage options suited to downstream electronic circuitry.
Matching the converter to a system requires consideration of the available input voltage under normal and abnormal conditions. Voltage drops, supply disturbances, and transient behaviour can influence whether the selected input range provides sufficient margin for the installation.
TDK-Lambda states that the CCG60 is certified to IEC, EN, UL, and CSA 62368-1 and supports operation at altitudes up to 5,000 metres. The series also carries a five-year warranty.
The new converter provides a higher-power option for equipment designs using the established CCG mechanical format. Its final operating capacity will depend on the selected output, the available cooling, the electrical installation, and the compliance requirements of the complete system.
