TPS28226 8-Pin Sink Synchronous MOSFET Drivers

Texas Instruments TPS28226 8-Pin High-Frequency 4A Sink Synchronous MOSFET Drivers is optimized for a variety of high-current one and multi-phase DC-to-DC converters. The Texas Instruments TPS28226 MOSFET Drivers have a small-size and low EMI emissions, providing a high-efficiency solution. Efficiency is achieved by up to 8.8V gate drive voltage, 14ns adaptive dead-time control, 14ns propagation delays, and high-current 2A source with 4A sink drive capability. The 0.4Ω impedance for the lower gate driver holds the gate of power MOSFET below its threshold. This feature ensures no shoot-through current at high dV/dt phase node transitions. Charged by an internal diode, the bootstrap capacitor allows the use of N-channel MOSFETs in a half-bridge configuration.
