UCC27211A 3.7A/4.5A Half-Bridge Driver

The UCC27211A device driver is based on the popular UCC27201 MOSFET drivers; but, this device offers several significant performance improvements. The peak output pullup and pulldown current has been increased to 3.7A source and 4.5A sink and +12V +100V VDD HB SECONDARY SIDE CIRCUIT HI PWM CONTROLLER LI DRIVE HO HI HS DRIVE LO LO UCC27211A VSS .
