TDK Corporation announces the introduction of additional models to the popular CCG series of isolated DC-DC converters. The 1.5 W and 3 W rated parts operate convection cooled at full load from -40 to +85° C. All voltage combinations are available with terminations for either surface-mount or through-hole placement. Applications include data and telecommunications, test, measurement, process control, broadcast and battery-powered equipment.

The new CCG1R5 (1.5 W) and CCG3 (3 W) models comprise 36 voltage and current combinations with 3.3 V, 5 V, 12 V, 15 V and dual +/-12 V and +/-15 V outputs. The dual output models can also be connected to supply 24 V and 30 V. All can operate from either 4.5 to 18 V, 9 to 36 V or 18 to 76 V_dc inputs to support operation from 5 V, 12 V, 24 V and 48 V power sources. This 4:1 input range can assist with inventory reduction programs with one part number covering two nominal voltages.

Both the 1.5 W and 3 W share a common compact package size of 15.7 x 10.4 x 11.5 mm (length x width x height). The plastic case is not encapsulated, avoiding quality risks associated with silicon potting compounds during reflow soldering.

Over-current protection and remote on/off is standard, with a -5/+10% output voltage adjustment range on single outputs only. Input to output isolation is 1,500 V_dc. Certification is to the IEC/UL/CSA/EN 62368-1 safety standards with the CE and UKCA marks for the Low Voltage and RoHS Directives.

Key Features of CCG1R5 and CCG3: 

• Wide 4:1 Input Ranges
• Space Saving Package Sizes
• Certified to IEC 62368-1
• Reduced Derating at High Ambient Temperatures
