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 30­minute warm-up period. Sense terminals are externally jumpered to their respective output terminals.
