DESCRIPTION (continued)
A differential line is used for the share bus to maximize noise immunity and accommodate different voltage drops
in each power converter’s ground return line. Trimming of each converter’s output voltage is accomplished by
injecting a small current into the output voltage sense line, which requires a small resistance (typically 20
to
100
) to be inserted.
These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam
during storage or handling to prevent electrostatic damage to the MOS gates.

(1) Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only,
and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is
not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. Voltages are with respect to
GND. Currents are positive into, and negative out of the specified terminal.
