IR21593SPBF

Lighting, Ballast Controllers Overview

The IR21593 is a high-voltage, high-speed power MOSFET and IGBT driver designed for half-bridge and full-bridge topologies. It integrates bootstrap diode and level-shifting circuitry to drive the high-side switch directly from a low-voltage control signal. The device operates with supply voltages up to 600V and features independent inputs for enhanced flexibility in resonant converter applications.
