描述 Description

The EiceDRIVER? 2EDF72x5K is a functional isolated gate driver designed for high-performance DC-DC medium-voltage, half- and full-bridge topologies. The 4A/8A source/sink currents, combined with a low 37ns propagation delay and the highly accurate timing over both temperature and production, are the perfect fit for high-frequency PWM control with tightest possible dead time windows, delivering highest conversion efficiency.
The very low impedance of the gate driver output stages keeps the driver package and PCB cooler, which is a key benefit in high density power brick converters. The device’s 4V UVLO and dead time control ensure that OptiMOS? half-bridge MOSFETs always run within their safe operating area. A CMTI of 150V/ns guarantees high robustness even for fast switching transients (di/dt) in the power loop. The EiceDRIVER? 2EDF7235K includes programmable DTC (dead time control) and an inverted SLDOP mode. All devices can operate in low cost bootstrapped high side supply and come in a cost competitive, small form factor LGA13 5mm x 5mm package.
