description (continued)

The TPS5300 includes high-side and low-side gate drivers rated at 2 A typical, that enable efficient operation

at higher frequencies and drive larger or multiple power MOSFETs (such as 50-A output current applications).

An adaptive dead-time circuit minimizes dead-time losses while preventing cross-conduction of high-side and

low-side switches. All three outputs power up together as they track the same user programmable slowstart

voltage. The enable external (ENABLE_EXT) terminal allows the TPS5300 to activate external switching

controllers for additional system power requirements.

protection, and user-programmable overcurrent protection, and is packaged in a small 32-pin TSSOP

PowerPAD package.
