UCC27201ADDAR
120 -V启动， 3 - A峰值，高频率，高侧/低侧驱动器 120-V Boot, 3-A Peak, High Frequency, High-Side/Low-Side Driver
DESCRIPON
The UCC27200A/1A family of high frequency N-Channel MOSFET drivers include a 120-V bootstrap diode and high-side/low-side driver with independent inputs for maximum control flexibility. This allows for N-Channel MOSFET control in half-bridge, full-bridge, two-switch forward and active clamp forward converters. The low-side and the high-side gate drivers are independently controlled and matched to 1-ns between the turn-on and turn-off of each other. The UCC27200A/1A are based on the popular UCC27200/1 drivers, but offer some enhancements.
