† Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES: 1. Unless otherwise specified, all voltages are with respect to PGND.
2. High-level input voltages on the ENABLE, SYNC, CROWBAR, IN, and DT terminals must be greater than or equal to VCC


Description

The TPS2830 and TPS2831 are MOSFET drivers for synchronous-buck power stages. These devices are ideal for designing a high-performance power supply using a switching controller that does not include suitable MOSFET drivers on the chip. The drivers are designed to deliver 2.4-A peak currents into large capacitive loads. Higher currents can be controlled by using multiple drivers in a multiphase configuration. The high-side driver can be configured as a ground-reference driver or as a floating bootstrap driver. An adaptive dead-time control circuit eliminates shoot-through currents through the main power FETs during switching transitions, and provides high efficiency for the buck regulator. The TPS2830/31 drivers have additional control functions:ENABLE, SYNC, and CROWBAR. Both drivers are off when ENABLE is low. The driver is configured as a nonsynchronous-buck driver when SYNC is low. The CROWBAR function turns on the low-side power FET,overriding the IN signal, for over-voltage protection against faulted high-side power FETs.

The TPS2830 has a noninverting input. The TPS2831 has an inverting input. The TPS2830/31 drivers are available in 14-terminal SOIC and TSSOP packages and operate over a junction temperature range of 40to 125
