ISL71441M GaN FET Half-Bridge Driver Evaluation Board

The ISL71441MEV1Z evaluation board evaluates the performance of the ISL71441M 12V GaN FET half-bridge driver in an open-loop buck configuration. The evaluation board includes the GaN FET half-bridge driver, Renesas GaN FETs, and a buck converter power stage inductor and output capacitors.

The ISL71441M is a radiation tolerant PWM input 12V half-bridge GaN FET driver designed to drive low r_DS(ON) Gallium Nitride (GaN) FETs for DC/DC switching regulators. An integrated programmable GaN FET gate drive voltage, high-side bootstrap switch, and strong gate drive current provide a compact and robust GaN FET half-bridge driver. The ISL71441M can interface directly to the ISL73847M dual-phase PWM buck controller to create a high-efficiency point-of-load (POL) regulator to power many of the latest low voltage, high current FPGA and DSP digital core rails.
