Pin Descriptions (continued)

Pin Name Description

EP PGND Exposed Pad / Power Ground — Electrical path for the power circuits within the module. PGND is not internally

connected to AGND (pin 5,6). Must be electrically connected to pins 5 and 6 external to the package. The exposed pad

is also used to dissipate heat from the package during operation. Use one hundred thermal vias from top to bottom

copper for best thermal performance.

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.

For soldering specifications, refer to the following document: www.ti.com/lit/snoa549c

(1) Absolute Maximum Ratings are limits beyond which damage to the device may occur. Operating Ratings are conditions under which

operation of the device is intended to be functional. For ensured specifications and test conditions, see the Electrical Characteristics.

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

specifications.

(3) The human body model is a 100pF capacitor discharged through a 1.5 kΩ resistor into each pin. Test method is per JESD-22-114.

Operating Ratings

(1)

VIN 6V to 20V

EN, SYNC 0V to 5.0V

Operation Junction Temperature −40°C to 125°C

(1) Absolute Maximum Ratings are limits beyond which damage to the device may occur. Operating Ratings are conditions under which

operation of the device is intended to be functional. For ensured specifications and test conditions, see the Electrical Characteristics.
