UCC27442-Q1 High-Speed Low-Side Gate Driver Texas Instruments UCC27442-Q1 Dual-Channel High-Speed Low-Side Gate Driver can drive MOSFET and GaN power switches effectively. UCC27442-Q1 has a typical peak drive strength of 4A, which reduces the rise and fall times of the power switches, lowering switching losses and increasing efficiency. The UCC27442-Q1 fast propagation delay (18ns typical) yields better power stage efficiency by improving the deadtime optimization, pulse width utilization, control loop response, and transient performance of the system.
