The ISL6605 is a high frequency MOSFET driver optimized to drive two N-Channel power MOSFETs in a synchronous rectified buck converter topology.
The ISL6605 is a high‑frequency, synchronous‑rectified MOSFET driver designed to drive two N‑Channel power MOSFETs in buck‑converter topologies. It operates from a single low‑voltage supply and offers fast propagation, low on‑resistance, and adaptive shoot‑through protection.
Key features include a typical 4 A sink current, 0.4 Ω on‑resistance, 8 ns propagation delay, and a three‑state PWM input. The device is offered in QFN and SOIC packages and includes detailed layout and MOSFET‑selection guidelines for high‑efficiency power‑regulator designs.
| Sink Current (Lower Gate) | 4 A |
|---|---|
| Propagation Delay | 8 ns |
| Operating Temperature Range | -40 °C to 85 °C |
The lower gate driver can sink up to 4 A.
Typical propagation delay is 8 ns.
A bootstrap capacitor of at least 0.125 µF is recommended.
