Notes to Specifications
1. Tested at each output.
2. Parameter guaranteed byline and load regulation tests.
3. Although operation with no load is permissible, light loading on the main (+5V) output may cause the output voltage of the auxiliary
outputs (±12V or ±15V) to drop out of regulation. It is therefore recommended that at least 100mA or 20% of the output power,
whichever is greater, be taken from the main (+5V) output and at least 50mA (or ±12V: 1.2W, ±15V: 1.5W) of the output power is
taken from the auxiliary (±12V or ±15V) .
4. Total combined output power –30W.
5. Bandwidth guaranteed by design. Tested for 20KHz to 2MHz.
6. An overload is that condition with a load in excess of the rated load but less than that necessary to trigger the overload protection
circuit and is the condition of maximum power dissipation.
7. Load step transition time between 2.0µs and 10µs.
8. Recovery time is measured from the initiation of the transient to where V_OUT has returned to within ±1.0% of V_OUT at 50% load.
9. Input step transition time between 2.0µs to 10µs.
10. Parameter shall be tested as part of design characterization and after design or process changes. Thereafter parameters shall be
guaranteed to the limits specified in the table.
11. Turn on delay time measurement is for either a step application of power at the input or the removal of a ground signal from the
inhibit pin (pin 8) while power is applied to the input.
