STMicroelectronics STRG02, STRG04 and STRG06 power-conversion ICs

Click2Contact

STMicroelectronics has implemented direct digital power conversion from 48 V by developing a family of ICs to support the complete range of data centre power-conversion applications. The direct digital power conversion eliminates intermediate conversion stages to minimise power loss in data centres from power distribution, as well as to reduce space and cooling requirements.

The STRG02, STRG04 and STRG06 ICs are fully compliant with Intel’s VR12.5 (Haswell and Broadwell), VR13 (Skylake) and DDR3/4 voltage-regulation specifications and all FPGAs and ASICs for data centre applications. The three chips, together with ST’s low-voltage StripFET power-MOSFET family, assure robust and efficient system operation at input voltages from 36 to 72 V, with output voltages between 0.5 and 12 V. These specifications confirm power efficiency of >97% at 12 V/500 W and high system bandwidth using minimal PCB space.
