Renesas Electronics Corporation has expanded its digital multiphase platform to 41 devices with the introduction of 15 new digital multiphase controllers and six smart power stages. The ISL6822x, ISL6823x, RAA2282xx digital multiphase controllers, and ISL993xx, RAA2213xx smart power stages support 10A up to 1000A+ digital computing loads for advanced CPUs, FPGAs, GPUs, and artificial intelligence (AI) ASICs addressing IoT infrastructure systems.
The 2nd generation Digital Multiphase Controllers provides scalability and flexibility without the phase doublers. Moreover, it becomes easy to find a controller for configuration within two-phase to 20 native phases. The on-chip non-volatile memory of the controller allows the device to save the entire configuration. The AVSBus interface of the devices enable connections to any general market ASIC or processor for monitoring and adaptive voltage positioning. The PMBus interface provides full monitoring of I/O voltages and currents, temperature, and fault reporting.
The 2nd generation smart power stages (SPS) provides a high level of integration coupled with current sensing capability. They integrate highly precise current sense and reporting. This eliminates the need for complex temperature and inductor DCR compensation.
The PowerNavigator software with GUI allows the Power designers to easily configure the controller, set the parameters to tune the system, and debug/monitor using the black box, high-speed command logging, and digital test bus features.
