ISL6334B, ISL6334C RECOMMOEIBSNSLDO6E3LD3E4RT, EEISPPLLR6A3OC3D4EUAMCETNT PART VR11.1, 4-Phase PWM Controller with Light Load Efficiency Enhancement and Load Current Monitoring Features DATASHEET FN6689 Rev 3.00 May 5, 2016 The ISL6334B, ISL6334C control microprocessor core voltage regulation by driving up to 4 interleaved synchronous-rectified buck channels in parallel. This multiphase architecture results in multiplying channel ripple frequency and reducing input and output ripple currents. Lower ripple results in fewer components, lower cost, reduced power dissipation, and smaller implementation area. Microprocessor loads can generate load transients with extremely fast edge rates and require high efficiency at light load. The ISL6334B, ISL6334C utilizes Intersil’s proprietary Active Pulse Positioning (APP), Adaptive Phase Alignment (APA) modulation scheme, active phase adding and dropping to achieve and maintain the extremely fast transient response with fewer output capacito...
