Electrical Specification

Typical at nominal line, full load & 25°C unless otherwise stated.

NOTE:
1. Measured from High Line to Low Line.
2. Measured from Full Load to No Load.
3. Output noise & ripple is measured with a 10µF tantalum & 1µF ceramic capacitor across the output.
4. It is recommended to put a 100µF capacitor with ESR<100mΩ across the input to reduce the input ripple voltage.
5. Suffix ‘N’ to model number for Negative Logic Remote On/Off Control.
