Vin = 28 V 10 % of Rated Output Voltage Overload Trip Current Ovld Maximum current at specified output voltage 105 135 % of Max Output Current Notes to Specifications Tables 1. Operation outside absolute maximum/minimum limits may cause permanent damage to the device. Extended operation at the limits may permanently degrade performance and affect reliability. 2. Device performance specified in Electrical Performance table is guaranteed when operated within recommended limits. Operation outside recommended limits is not specified. 3. Parameter measured from 28V to 18V or to 50V while load remains fixed at 10%, 50% and 100% of Imax. 4. Parameter measured from 50% to 10% or 100% of maximum load conditions while line remains fixed at 18, 28 or 50 volts. 5. Guaranteed for a bandwidth of DC to 20 MHz. Tested using a 20 KHz to 2.0 MHz bandwidth. 6. A capacitive load of any value from 0 to the specified maximum is permitted without compromise to DC performance. A capacitive load in excess of the maximum limit may interfere with the proper operation of the converter’s short circuit protection, causing erratic behavior during turn on. 7. Parameter is tested as part of design characterization or after design or process changes. Thereafter, parameters shall be guaranteed to the limits specified in the table. 8. Load transient rate of change, di/dt ≤ 2.0 A/µs. 9. Recovery time is measured from the initiation of the transient to where V OUT has returned to within ±1% of its steady state value. 10. Line transient rate of change, dv/dt ≤ 50 V/µs. 11. Turn on delay time is for either a step application of input power or a logical low to high transition on the enable pin (pin 3) while power is present at the input. |
