Notes
1
Specifications typical at Ta=+25℃, resistive load, nominal input voltage and rated output current unless otherwise noted.
2
Ripple & Noise measurement bandwidth is 0-20MHz, with 10µF, tantalum capacitor and 1µF ceramic capacitor.
3
All DC/DC converters should be externally fused at the front end for protection.
4
Specifications are subject to change without notice.
