The UCC27201A-Q1 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 drivers are independently controlled and matched to 1ns between the turn-on and turn-off of each other. In order to improve performance in noisy power supply environments the UCC27201A-Q1 has the ability to withstand an absolute 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.

The UCC27201A-Q1 has TTL-compatible thresholds and is offered in an 8-pin SOIC with a thermal pad.
