Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. These ratings apply when the current is
limited to less than 1.2 mA for pins 1, 2, 3, and 6. Operating ratings indicate conditions for which the device is intended to be functional,
but device parameter specifications may not be ensured under these conditions. For ensured specifications and test conditions, see the
Electrical Characteristics.
If Military/Aerospace specified devices are required, please contact the TI Sales Office/ Distributors for availability and specifications.
Note that switch current and output current are not identical in a step-up regulator. Output current cannot be internally limited when the
LM2588 is used as a step-up regulator. To prevent damage to the switch, the output current must be externally limited to 5A. However,
output current is internally limited when the LM2588 is used as a flyback regulator (see the Application Hints section for more
information).
The junction temperature of the device (T J ) is a function of the ambient temperature (T A ), the junction-to-ambient thermal resistance
( θ JA ), and the power dissipation of the device (P D ). A thermal shutdown will occur if the temperature exceeds the maximum junction
temperature of the device: P D × θ JA + T A(MAX) ≥ T J(MAX) . For a safe thermal design, check that the maximum power dissipated by the
device is less than: P D ≤ [T J(MAX) ? T A(MAX) ]/ θ JA . When calculating the maximum allowable power dissipation, derate the maximum
junction temperature—this ensures a margin of safety in the thermal design.
