iP2005CPbF PD-60360 Synchronous Buck Optimized LGA Power Block Features Description 40A Multiphase building block No derating up to T = 95C The iP2005C is a fully optimized solution for PCB high current synchronous buck multiphase Optimized for low power loss applications. Board space and design time are Bias supply range of 4.5V to 7.0V greatly reduced because most of the Operation up to 1.5MHz components required for each phase of a Bi-directional current flow typical discrete-based multiphase circuit are Under Voltage Lockout integrated into a single 7.65mm x 7.65mm x LGA interface 1.66mm power block. The only additional 7.65mm x 7.65mm outline components required for a complete multiphase converter are a PWM controller, the Applications output inductors, and the input and output Multi-phase Architectures capacitors.
