This Short pin lengths available product family provides up to 100 watts of power or 40A of output current Positive remote On/Off th (1.8V and below) in an industry standard 1/16 brick form factor (1.30 x Heat spreader 0.90). The 5V output offers one of the highest output currents available and provides up to 91.5% efficiency at full load. With creative design technology and optimization of component placement, these converters possess outstanding electrical and thermal performance, as well as extremely high reliability under highly stressful operating conditions. All modules are protected from abnormal input/output voltage, current, and temperature conditions. For lower power needs, but in a similar small APPLICATIONS form factor, please check out Delta V36SE (50W), S48SP (36W or 10A) Optical Transport and S36SE (17W or 5A) series standard DC/DC modules.
