Static Characteristics

Notes:

1. Output voltage tolerance includes the the effects of set point

accuracy, line regulation and load regulation.

2. Ripple and noise is measured at 20 MHz bandwidth using

a 12 inch twisted pair wire to connect to the power supply

terminals. A 0.1

µF and a 47 µF capacitor are connected in

parallel as close to the power supply terminals as possible.

3. Overvoltage protection is provided by a “hiccup mode” circuit.

The unit recovers automatically when the fault condition is

removed.

4. Overload protection is provided by a foldback current limit-

ing circuit. The unit recovers automatically when the fault

condition is removed. For the 3.3V output model, overload

protection is set to operate between 36 to 55W.

5. Mounting holes M1 and M2 should be grounded for EMI

purposes.

6. It is recommended that a fuse be used on the input of a power

supply for protection. See the mechanical diagram for the

correct rating.
