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 0-20 MHz.

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.
