This slide captures transient test data collected using the Competitor A controller on the left and the Renesas digital multiphase controller solution to the right. To ensure accurate comparison of transient and thermal data, a purpose built development platform was created using the Renesas digital multiphase controller and accompanying Smart Power Stages with the exact layout, board stack up and BOM content. In this example, V_IN = 12 V, V_OUT = 1 V; both boards supported an exact output capacitance of 4000 µF, switching frequency of 500 kHz, and an applied load of 90 A at 50 A/µs slew rate. As is evident in the performance data collected, the Renesas solution supports a worst case 3% deviation for V_OUT vs. 5% for the competing solution. Moreover, it should be noted that the zero latency associated with Renesas' control loop allows it to recover three times faster than the competing constant on-time solution from Competitor A.
