IR3548 Overview
The IR3548 is a dual integrated PowIRstage® is a with 2 pairs of co-packed control and synchronous MOSFETs and an optimized dual phase driver. The package is optimized internally for PCB layout, heat transfer and package inductance. The integrated driver is capable of operating as a Dual driver (2 PWM controlling 2 phases), a Doubler driver (1 PWM controlling 2 phases) or a Quad driver (1 PWM controlling 4 phases in...
