IR3556 Datasheet (International Rectifier) - synchronous buck gate driver

IR3556, synchronous buck gate driver

The IR3556 integrated PowIRstage® contains a synchronous buck gate driver IC which is co-packed with control and synchronous MOSFETs and a Schottky diode to further improve efficiency.

The package is optimized for PCB layout, heat transfer, driver/MOSFET control timing, and minimal switch node ringi
