Endura Technologies has announced the ET21324X, a new high-current-density multiphase step-down integrated voltage regulator (IVR) designed for artificial intelligence (AI) and high-performance computing (HPC) power delivery requirements. According to Endura Technologies, the ET21324X targets next-generation compute platforms by providing rapid transient load response and minimal voltage droop, key factors for modern data center architectures.
The ET21324X delivers up to 150 A of continuous output current and 220 A of instantaneous current, with transient load response in nanoseconds and voltage droop limited to less than 30 mV. The device leverages Endura Technologies’ proprietary BDDC control architecture, supporting fast load transient responses exceeding 10 A per nanosecond, recovery times under 200 nanoseconds, and dynamic voltage scaling capability greater than 1 V per 200 nanoseconds.
Designed for scalability in high-density environments, the ET21324X allows up to 61 units to be connected in parallel, supporting multi-domain configurations for higher aggregate current. It operates at programmable switching frequencies from 40 to 150 MHz and complies with AVSBus Revision 1.4 and 2.0 specifications. Endura Technologies claims this high bandwidth and current density are well suited for powering AI processors, central processing units (CPUs), graphics processing units (GPUs), application-specific integrated circuits (ASICs), and field-programmable gate arrays (FPGAs) — all key components in data center infrastructure and hyperscale computing.
“The ET21324X provides the bandwidth, current capability, and dynamic behavior required to support these next-generation designs,” said Dr. Davood Yazdani, CPO at Endura Technologies. “Its low voltage droop, fast transient response, high scalability, and fine-grained voltage control give system architects the flexibility to maximize performance per watt.”
The company states that its digital architecture is designed to efficiently scale with advanced process nodes and data center chiplet architectures, positioning the ET21324X as a solution for demanding AI workflows and HPC workloads that require precise, rapid, and reliable power delivery.
