Notes :
1. Specifications typical at Ta=+25], resistive load, nominal input voltage, 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 0-20 MHz. 4. These power converters require a minimum output loading to maintain specified regulation. 5. Operation under no-load conditions will not damage these modules; however, they may not meet all specifications listed.
