16 phase 1kA voltage regulator aims at AI and 5G
Infineon Technologies has extended its portfolio of high current system chipsets with a 16-phase digital PWM multiphase controller.

The XDPE132G5C enables currents up to 1000A for next generation CPUs, GPUs, FPGA and ASICs used in high-end artificial intelligence (AI) servers and 5G datacom applications. With a true 16-phase digital PWM engine and an improved advanced transient algorithm, the XDPE132G5C controller addresses these high phase count requirements. The true active current sharing between phases enables a reliable, compact and cost-saving design. There is no need for extra logic doubler ICs commonly utilized in today’s high phase count markets. For leading edge ASICs and FPGAs, the XDPE132G5C offers fine V out setting in 0.625mV increments. In addition, it supports communication market auto-restart requirements with options to reduce remote site maintenance following power or system glitches. The chip comes in a 7x7mm 56-pin QFN to accommodate 16 phases. It employs a full digital and programmable load line and is PMBus 1.3/AVS compliant delivering a comprehensive suite of telemetry features.
