Notes
➀ Unless otherwise noted, all specifi cations are at nominal input voltage, nominal output voltage and
full load.
General conditions are +25˚ Celsius ambient temperature, near sea level altitude, natural convec-
tion airfl ow.
All models are tested and specifi ed with external parallel 1 µF and 10 µF multi-layer ceramic
output capacitors.
A 220uF external input capacitor is used. All capacitors are low-ESR types wired close to the
converter.
➁ Input (back) ripple current is tested and specifi ed over 5 Hz to 20 MHz bandwidth. Input fi ltering is
Cbus=220 µF, Cin=33 µF and Lbus=12 µH.
➂ All models are stable and regulate to specifi cation under no load.
➃ The Remote On/Off Control is referred to -Vin. For external transistor control, use open collector
logic or equivalent.
