120V Boot, 3-A Peak, High Frequency, High-Side/Low-Side Driver

120V Boot, 3-A Peak, High Frequency, High-Side/Low-Side Driver - UCC27201A
 

Description

The UCC2720xA 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. The UCC2720xA are based on the popular UCC27200/1 drivers, 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 –18 V 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.

Two versions of the UCC27200A are offered. The UCC27200A has high-noise immune CMOS input thresholds while the UCC27201A has TTL-compatible thresholds.

Both devices are offered in an 8-pin SOIC (D), PowerPad SOIC-8 (DDA), SON-8 (DRM) package, a 9-pin SON-9 (DRC) package and a 10-pin SON-10 (DPR) package.
