Specifications
Table A-1 lists the specifications of the dc source. Unless otherwise noted, specifications are warranted
over the ambient temperature range of 0 to 55 °C. Specifications apply with typical cellular phone
capacitive loads from 0µF to 12,000µF. Sensing is at the rear terminals of the power supply after a 30-
minute warm-up period. Sense terminals are externally jumpered to their respective output terminals.

1
From 45° to 55° average current derates linearly from 3 A to 2.5 A. All other specifications are unaffected.
2
Peak current for up to a 7 millisecond time period. Average current over 11.7 milliseconds cannot exceed 3 A.
3

4
Specification applies for output voltages greater than 10mV.
5
Applies with current detector set to DC. In ACDC mode the offset is 4 times the specified value for +current and 2.6 mA for
negative current.
6
Specification is for phone capacitance greater than 5µF.
