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.

Absolute Maxmum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for

which the device is intended to be functional, but device parameter specifications may not be specified under these conditions. For

specified specifications and test conditions, see Electrical Characteristics.

If Military/Aerospace specified devices are required, please contact the TI Sales Office/ Distributors for availability and specifications.

(3)

The human body model is a 100 pF capacitor discharged through a 1.5 k

Ω resistor into each pin.

(4)

The maximum allowable power dissipation is calculated by using PDMAX = (TJMAX − TA)/θJA, where TJMAX is the maximum junction

temperature, TA is the ambient temperature, and θJA is the junction-to-ambient thermal resistance of the specified package. The 893

mW rating results from using 150°C, 25°C, and 140°C/W for TJMAX, TA, and θJA respectively. A θJA of 140°C/W represents the worst-

case condition of no heat sinking of the 16-pin TSSOP package. Heat sinking allows the safe dissipation of more power. The Absolute

Maximum power dissipation must be derated by 7.14 mW per °C above 25°C ambient. The LM2653 actively limits its junction

temperatures to about 165°C.

All limits specified at room temperature (standard typeface) and at temperature extremes (bold typeface). All room temperature limits

are 100% production tested. All limits at temperature extremes are specified via correlation using standard Statistical Quality Control

(SQC) methods. All limits are used to calculate Average Outgoing Quality Level (AOQL).
