Information

The ISL6333 three-phase PWM family of control ICs provide a precision voltage regulation system for advanced microprocessors. The integration of power MOSFET drivers into the controller IC marks a departure from the separate PWM controller and driver configuration of previous multi-phase product families. By reducing the number of external parts, this integration is optimized for a cost and space saving power management solution The ISL6333 controllers also include advanced control loop features for optimal transient response to load application and removal. One of these features is highly accurate, fully differential, continuous DCR current sensing for load line programming and channel current balance. Active Pulse Positioning (APP) Modulation and Adaptive Phase Alignment (APA) are two other unique features, allowing for quicker initial response to high di/dt load transients. With this quicker initial response to load transients, the number of output bulk capacitors can be reduced, helping to reduce cost.
