The SYNC pin can be used regardless of load to disable the synchronous FET driver and operate the power

supply nonsynchronously.

voltage reaches the threshold and the regulator output is stable. This function ensures both FET drivers are off

The TPS2838/39/48/49 devices are offered in the thermally enhanced 14-pin and 16-pin PowerPAD TSSOP

package. The PowerPAD package features an exposed leadframe on the bottom that can be soldered to the

printed-circuit board to improve thermal efficiency. The TPS2838/48 are noninverting control logic while the

TPS2839/49 drivers are inverting control logic.
