1 Introduction

Developed for high voltage applications where isolation and reliability is required, the UCC2x5xx delivers reinforced isolation of 5.7 kVRMS and a surge immunity tested up to 12.8 kV along with a common-mode transient immunity (CMTI) greater than 100 V/ns. It has the industry’s fastest propagation delay of 19 ns and the tightest channel-to-channel delay matching of less than 5 ns to enable high-switching frequency, high-power density, and efficiency.

The flexible, universal capability of the UCC2x5xx with up to 18-V VCCI and 25-V VDDA/VDDB allows the device to be used as a low-side, high-side, high-side/low-side, or half-bridge drivers with dual PWM input or single PWM input. With its integrated components, advanced protection features (UVLO, dead time and enable/disable), and optimized switching performances, the UCC2x5xx enables designers to build smaller, more robust designs for enterprise, telecom, automotive, and industrial applications with a faster time to market.
