High-Performance 1EDN8550B Single-Channel EiceDRIVER™ Gate Driver IC

The 1EDN8550B from Infineon Technologies represents a significant advancement in gate driver IC technology, specifically engineered to meet the rigorous demands of modern power conversion systems. As a member of the EiceDRIVER™ family, this single-channel driver is designed to deliver exceptional switching performance, enhanced system reliability, and superior noise immunity, making it an ideal solution for high-frequency applications such as server SMPS, telecom power supplies, and industrial motor drives.

A key feature of the 1EDN8550B is its robust 5 A source and sink current capability, which enables fast switching of power MOSFETs and IGBTs. This high drive strength minimizes switching losses, a critical factor for improving overall system efficiency, particularly in high-frequency circuits operating under heavy loads. The device supports rail-to-rail output voltages up to 20 V, providing ample drive voltage margin for various power semiconductor technologies.

The driver incorporates advanced functional integration, including under-voltage lockout (UVLO) protection for both the primary and secondary sides, which prevents faulty operation under insufficient supply conditions. Its very high common-mode transient immunity (CMTI) of ±200 kV/µs ensures stable operation in noisy environments, effectively preventing unintended cross-conduction in half-bridge topologies.

Housed in a compact DSON-8 package, the 1EDN8550B offers excellent thermal performance and a small footprint, supporting high-density PCB designs. Its low propagation delay and tight channel-to-channel matching further enhance control precision, making it suitable for phase-shifted full-bridge and synchronous rectification circuits.

ICGOOODFIND: The 1EDN8550B EiceDRIVER™ sets a high standard for performance and integration in gate driver ICs, offering designers a reliable, high-efficiency solution for next-generation power electronics.
