UCC27211DDAR 120-V Boot, 4-A Peak, High-Frequency High-Side and 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. The input structure is now able to directly handle –10 VDC, which increases robustness and also allows direct interface to gate-drive transformers without using rectification diodes. The inputs are also independent of supply voltage and have a maximum rating of 20-V.

Features
• Drives Two N-Channel MOSFETs in High-Side
   and Low-Side Configuration With Independent
   Inputs
• Maximum Boot Voltage 120-V DC
• 4-A Sink, 4-A Source Output Currents
• 0.9-Ω Pullup and Pulldown Resistance
• Input Pins Can Tolerate –10 V to 20 V and Are
   Independent of Supply Voltage Range
• TTL or Pseudo-CMOS Compatible Input Versions
• 8-V to 17-V VDD Operating Range, (20-V
   Absolute Maximum)
• 7.2-ns Rise and 5.5-ns Fall Time With 1000-pF
   Load
• Fast Propagation Delay Times (18 ns Typical)
• 2-ns Delay Matching
• Symmetrical Undervoltage Lockout for High-Side
   and Low-Side Driver
• All Industry Standard Packages Available (SOIC-
   8, PowerPAD™ SOIC-8, 4-mm × 4-mm SON-8
   and 4-mm × 4-mm SON-10)
• Specified from –40 to 140 °C

Applications
• Power Supplies for Telecom, Datacom, and
   Merchant
• Half-Bridge and Full-Bridge Converters
• Push-Pull Converters
• High-Voltage Synchronous-Buck Converters
