TPS28225 8 引脚高频 4A 吸入电流同步 MOSFET 驱动器

TPS28225 描述

The TPS28225 and TPS28226 are high-speed drivers for N-channel complimentary driven power MOSFETs with adaptive dead-time control. These drivers are optimized for use in variety of high-current one and multi-phase dc-to-dc converters. The TPS28225/6 is a solution that provides highly efficient, small size low EMI emmissions.

The performance is achieved by up to 8.8-V gate drive voltage, 14-ns adaptive dead-time control, 14-ns propagation delays and high-current 2-A source and 4-A sink drive capability. The 0.4-Ω impedance for the lower gate driver holds the gate of power MOSFET below its threshold and ensures no shoot-through current at high dV/dt phase node transitions. The bootstrap capacitor charged by an internal diode allows use of N-channel MOSFETs in half-bridge configuration.
