资 源 简 介
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. Undervoltage 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 UCC2720x are offered — the UCC27200 has high-noise-immune CMOS input thresholds, and the UCC27201 has TTL-compaTIble thresholds.
