PWM Doubler/Quad Logic
Package Type: DFN 2 mm x 2 mm
IR3599/IR3599A is a phase multiplier which is designed to double or quadruple the effective maximum phase count from the controller, enabling a well-controlled, high phase count voltage regulator. Each IR3599/IR3599A is able to drive up to four independent power stages from one PWM input. The IR3599/IR3599A can be configured as DOUBLER logic where one PWM signal is internally split to drive the two power stages 180° out of phase, each at half of the PWM input frequency. The IR3599/IR3599A can also be configured as QUAD logic where one PWM signal is internally split at 0º, 90º, 180º, and 270º respectively, and each at 1/4 of the PWM input frequency. IR3599A features the patented IR Active Tri-Level (ATL) PWM input and output, designed to work with IR digital multi-phase controller and IR PowIRstage. The unique doubler/quad mode ATL tri-state timing allows the VR to transition into tri-state faster during load releases. IR3599 features industry’s standard tri-state PWM input and output interfaces, designed to work with general multi-phase controllers, drivers or power stages. IR3599/IR3599A also incorporates a power-on reset feature, which ensures the device is active only after the supply voltage exceeds a certain minimum operating threshold.
