Texas Instruments UCC2720xA 120V High-Side / Low-Side Drivers

Texas Instruments UCC2720xA 120V, 3A Peak High-Side / Low-Side Drivers are high-frequency N-Channel MOSFET drivers that include a 120V bootstrap diode and high side / low-side driver with independent inputs for maximum control flexibility. The TI UCC2720xA allows for N-channel MOSFET control in half-bridge, full-bridge, two-switch forward, and active clamp forward converters. The low-side and high-side gate drivers are independently controlled and matched to 1ns between the turn-on and turn-off of each other. TI UCC2720xA drivers offer an enhanced ESD structure compared with the UCC2720x and can withstand a maximum of -18V on its HS pin.
