TDK Corporation announces the introduction of two additional options to the TDK-Lambda brand CCG series of 1.5 W to 10 W isolated DC-DC converters. The newly available two-sided board coating provides extra protection for use in harsh environments, including rail and industrial applications. Also introduced is a larger, 40-piece tray size, providing easier placement of the surface mount models.
The series comprises 144 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 configured to supply single 24 V and 30 V outputs. All models can operate from a range of 4.5 to 18 V, 9 to 36 V, or 18 to 76 Vdc inputs to support operation from 5 V, 12 V, 24 V, and 48 V 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 1.5 W and 3 W units measure 15.7 x 10.4 mm (L x W), with the 6 W and 10 W models measuring 19 x 12.4 mm (L x W). The plastic case is not encapsulated, avoiding quality risks associated with silicone potting compounds during reflow soldering.
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 series can operate in ambient temperatures of -40 up to +100°C (model dependent) using convection or forced air cooling. Input to output isolation is 1,500 Vdc. The 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.
