Description
The TLD is a series of high-density, 3/4-brick DC/DC converters that provide standard telecom and datacom
input voltage conversion to two independently regulated output voltages. The TLD's leading-edge
technology provides high efficiency. Its thermal design enables delivery of full-rated power at 50°C ambient
temperature with 200 LFM forced air without addition of a heatsink. The outputs also track each other during
both startup and shutdown.
