UCC27211DDAR

120 -V启动， 4 - A峰值，高频高侧/低侧驱动器 120-V Boot, 4-A Peak, High Frequency High-Side/Low-Side Driver

Description

The UCC27210 and UCC27211 drivers are based on the popular UCC27200 and UCC27201 MOSFET

drivers, but offer several significant performance improvements. Peak output pull-up and pull-down

current has been increased to 4-A source and 4-A sink, and pull-up and pull-down resistance have been

reduced to 0.9 Ω, thereby allowing for driving large power MOSFETs with minimized switching losses

during the transition through the Miller Plateau of the MOSFET.
