1-2011 2 Applications • HEV and BEV battery chargers • Isolated converters in DC-DC and AC-DC power supplies • Server, telecom, it and industrial infrastructures • Motor drive and DC-to-AC solar inverters • LED lighting • Inductive heating • Uninterruptible power supply (UPS) 3 Description The UCC21520 and the UCC21520A are isolated dual-channel gate drivers with 4-A source and 6-A sink peak current.
It is designed to drive power MOSFETs, IGBTs, and SiC MOSFETs up to 5-MHz with best-in-class propagation delay and pulse-width distortion.
The input side is isolated from the two output drivers by a 5.
7-kVRMS reinforced isolation barrier, with a minimum of 100-V/ns common-mode transient immunity (CMTI).
Internal functional isolation between the two secondary-side drivers ...
