Renesas Electronics Corporation ISL6609AIRZ

The ISL6609A is a synchronous rectified MOSFET driver designed to control two N-Channel power MOSFETs in a synchronous-rectified buck converter topology, typically paired with Intersil multiphase PWM controllers for high-efficiency core voltage regulation in advanced microprocessors. It operates from a single 5V supply and features adaptive shoot-through protection, a 4A typical sink current for the lower gate driver, and an integrated bootstrap diode with overcharge prevention. The ISL6609AIRZ variant is packaged in an 8-lead 3mm × 3mm QFN with an exposed thermal pad, compliant with JEDEC MO-220 standards. It is rated for an ambient temperature range of -40°C to +85°C, is RoHS compliant, and meets the Pb-free reflow profile requirements of IPC/JEDEC J-STD-020.
