Endura Technologies has introduced the ET21324X, a quad-channel integrated voltage regulator intended for high-current point-of-load conversion in AI and high-performance compute platforms. The device is specified to deliver 150 A continuous output current with 220 A instantaneous capability and targets power rails that must hold regulation under rapid load steps from processors and accelerators.
The ET21324X uses a proprietary DC-DC switching and control approach to improve transient behavior. The device is specified for load-transient response rates greater than 10 A/ns, with less than 30 mV voltage droop and recovery times under 200 ns. These characteristics are intended to reduce rail disturbance during fast compute workload changes and enable tighter voltage margins.
The platform supports high current density above 4 A/mm² and dynamic voltage scaling faster than 1 V per 200 ns to support fine-grained power management. Switching frequency is programmable from 40 MHz to 150 MHz, enabling designers to trade off component size, losses, and control bandwidth based on rail requirements and board constraints.
For multi-rail and multi-domain systems, the ET21324X supports parallel operation to increase total current delivery. Up to 61 devices can be connected in parallel to scale output capacity for high-power CPU, GPU, ASIC, and FPGA platforms. The device supports AVSBus Rev 1.4 and 2.0 for adaptive voltage scaling and digital control integration in compute systems.
