DC-DC converter adds two-sided board coating, cuts silicone potting
TDK has launched two options for its 10W CCG isolated DC-DC converter series for use in harsh environments.
A two-sided board coating for the DC-DC converter range provides extra protection for use in harsh environments, including rail and industrial applications, while a larger, 40-piece tray size, providing easier placement of the surface mount models.
The unencapsulated DC-DC converter family also eliminates silicone potting compounds to avoid any quality risks associated with the materials during reflow soldering.
The TDK-Lambda CCG series comprises 144 voltage and current combinations with 3.3V, 5V, 12V, 15V, and dual +/-12V and +/-15V outputs. The dual output models can also be configured to supply single 24V and 30V outputs. All models can operate from a wide range of 4.5 to 18V, 9 to 36V, or 18 to 76Vdc inputs to support operation from 5V, 12V, 24V, and 48V DC power sources. The 4:1 input range assists inventory reduction programs and procurement management, with one part number covering two nominal input voltages.
The 1.5W and 3W units measure 15.7 x 10.4mm (L x W), with the 6W and 10W models measuring 19 x 12.4mm (L x W).
Using the trim function, single output models can be adjusted down to -5 and up to +10% of nominal to compensate for printed circuit board voltage drops. Overcurrent protection and remote on/off are standard on all models. The on/off function can also be used to put the converters into stand-by mode. This reduces the off-load power consumption to less than 0.1W, extending the time between battery charges on portable equipment.
The CCG DC-DC converter series can operate in ambient temperatures of -40 up to +100°C using convection or forced air cooling in applications such as rail rolling stock and trackside equipment, robotics, data and telecommunications, test, measurement, harsh environment process control, broadcast, and battery powered equipment.
The input to output isolation is 1,500Vdc and the DC-DC converter models are certified to IEC/UL/CSA/EN 62368-1 safety standards with the CE and UKCA marks for the Low Voltage and RoHS Directives.
