This product family provides up to 100 watts of power or 40A of Short pin lengths available th output current (1.8V and below) in an industry standard 1/16 brick Positive remote On/Off form factor (1.30 x 0.90). The 1.8V output offers one of the highest Heat spreader output currents available and provides up to 88.5% 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 form factor, please check APPLICATIONS out Delta, V36SE (50W or 15A), S48SP (36W or 10A) and S36SE Optical Transport (17W or 5A) series standard DC/DC modules.
