Power Derating Curve 
Output Power (%)
Notes 
1 Specifications typical at Ta=+25℃, resistive load, nominal input voltage and rated output current unless otherwise noted. 
2  Transient recovery time is measured to within 1% error band for a step change in output load of 75% to 100% 
3  Ripple & Noise measurement bandwidth is 0-20MHz. 
4  These power converters require a minimum output loading to maintain specified regulation, operation under no-load conditions will not 
damage these modules; however they may not meet all specifications listed. 
5  All DC/DC converters should be externally fused at the front end for protection. 
6  Specifications subject to change without notice.
