UCC27201 is a 120 V boot, 3-A peak, high frequency, high-side/low-side driver

This post sponsored by Texas Instruments.

The UCC27200/1 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. An on-chip bootstrap diode eliminates the external discrete diodes. Under-voltage lockout is provided for both the high-side and the low-side drivers forcing the outputs low if the drive voltage is below the specified threshold.

Two versions of the UCC27200 are offered. The UCC27200 has high noise immune CMOS input thresholds while the UCC27201 has TTL compatible thresholds. Both devices are offered in 8-pin SOIC (D), PowerPad SOIC-8 (DDA) and SON-8 (DRM) packages. UCC27201 is specified from -40 °C to 140 °C. Applications include power supplies for telecom, datacom, and merchant markets; half-bridge applications and full-bridge converters; isolated bus architecture; two-switch forward converters; active-clamp forward converters; high voltage synchronous-buck converters; as well as class-D audio amplifiers.
