DATASHEET
XPHASE3 TM POL CONTROL IC
DESCRIPTION
The IR3513 Control IC provides overall control of a scalable number of phases along with an internal gate driver,
current sense/sharing, and PWM. This allows the IR3513 to implement a stand-alone single-phase regulator or
interface with additional Phase ICs to develop a power solution with any number of phases. With this arrangement,
the final solution requires only 1 IC per phase to deploy 1 to X phases. Other approaches require a control IC plus 1
to X driver ICs or scalable “all-in-one” ICs that do not utilize all IC pins or circuitry leading to increased solution cost
and size.
