DESCRIPTION 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 two IR3548s).
Up to 1.
5MHz switching frequency enables high performance transient response, allowing miniaturization of output inductors, as well as input and output capacitors while maintaining industry leading efficiency.
Integrating two phases in one package while still providing superior efficiency and thermal performance, the IR3548 enables smallest size and lower solution cost.
The lower quiescent current makes it suitable for next generation VR12.
6/VR12.
