The UCC27201ADDA is a high-frequency N-channel MOSFET Driver includes a 120V 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 driver is independently controlled and matched to 1ns between the turn-ON and turn-OFF of each other. The UCC2720xA is based on the popular UCC27200/1 driver, but offer some enhancements. In order to improve performance in noisy power supply environments the UCC2720xA has an enhanced ESD input structure and also has the ability to withstand a maximum of -18V on its HS pin. 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.
