International Rectifier IR3588 CHiL digital control IC

International Rectifier has introduced the IR3588 CHiL digital control IC and IR3552 and IR3548 single- and dual-phase PowIRstage devices. The products meet Intel’s VR12.6 specifications for 15 W and 25 W Ultrabook laptop computers that significantly extend battery life.

The digital control IC and the optimised single-phase and dual-phase PowIRstage devices reduce footprint by more than 50% compared to leading monolithic solutions and offer a 40% smaller footprint compared to alternative reference designs. Additionally, battery life is extended as a result of the low quiescent current while offering lower operating current and sleep state power of less than 1 mW. This exceeds Intel’s VR12.6 Ultrabook power specifications. Battery life is further enhanced with IR’s Regenerative Braking technique which returns energy to the battery that is normally lost when waking a laptop computer from a sleep state.
