The CC3-0503SR-E is a 3W isolated DC-DC converter from the CC-E series, operating from a 4.5 to 9V input and delivering a 3.3V single output with a maximum current of 0.8A. It features surface mount (R) packaging, an efficiency of 73% at nominal input, and operates within an ambient temperature range of -40 to 85°C. The converter has a five-sided metal case for reduced radiated noise, an input-to-output isolation of 500Vac, and supports remote on/off via negative logic. Output voltage tolerance is ±3%, with ripple and noise specified at 120mV (40mV typical). No minimum load is required, and overcurrent protection activates in hiccup mode above 105% load. The part meets IEC/UL/CSA/EN62368-1
The DC-DC converter is a type of switching power supply that converts direct currents of buslines into direct currents that are needed for devices. TDK has a lineup of DC-DC converters under the TDK-Lambda brand for the industrial equipment market boasting high-reliability and long service life made possible with advanced circuit designing technology and high-density mounting technology. The lineup of DC-DC converters by TDK-Lambda also includes isolated and non-isolated types to meet various applications along with onboard, power module and unit types and a wide range of industry-standard sizes from brick-shaped to inch-sized.
