Description
The new E2S15 series of single-output DC/DC converters, offer unprecedented density and performance in
an eighth brick, which is 40% smaller than the traditional quarter-brick footprint. Patent pending technology
combined with thermally optimized construction allows the E2S15 to provide 15A of output current in an
8.5mm package without a heatsink. And the E2S15 series requires minimal derating to operating in high
ambient temperatures. The 100% surface mount design provides consistent high quality and reliability and
the SMT mounting option eliminates the need for separate (additional manual) operations to mount the
converters to the motherboards during mass production.
