SNVS377A – FEBRUARY 2006 – REVISED MARCH 2013

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 maximum ratings indicate limits beyond which damage to the device may occur. Operating Ratings are conditions under which

operation of the device is ensured. For ensured performance limits and associated test conditions, see the Electrical Characteristics

table. Functional temperature range is the range within which the device performs its intended functions, but not necessarily meeting the

limits specified in the Electrical Characteristic table.

If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/ Distributors for availability and

specifications.

The SW pin can have -2V to -0.5 volts applied for a maximum duty cycle of 10% with a minimum frequency of 1Hz. There is no duty

cycle or maximum period limitation for a SW pin voltage range of -0.5V to 30 Volts.

(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 TSSOP

rating of 1.56W results from using 150°C, 25°C, and 80°C/W for TJMAX, TA, and θJA respectively. The θJA of 90°C/W represents the

worst-case condition with no heat sinking of the 48-Pin TSSOP. Heat sinking allows the safe dissipation of more power. The Absolute

Maximum power dissipation should be de-rated by 12.5mW per °C above 25°C ambient. The SQA rating of 5.2W results from using

150°C, 25°C, and 24.2°C/W for TJMAX, TA, and θJA respectively. The Absolute Maximum power dissipation should be de-rated by 41mW

per °C above 25°C ambient. The LM27213 actively limits its junction temperature to about 150°C.

For testing purposes, ESD was applied using the human-body model, a 100pF capacitor discharged through a 1.5k

Ω resistor.

All limits are specified at room temperature (standard face type) and at temperature extremes (bold face type). All room temperature

limits are 100% production tested. All limits at temperature extremes are ensured via correlation using Statistical Quality Control (SQC)

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