OptiMOS 5 IPOL Buck Regulators For Subsequent-Gen Server And Telecom Functions

Infineon introduces OptiMOS built-in POL DC-DC regulators with a quick COT engine plus SVID and I²C/PMBus digital interfaces.

As know-how advances and scales all the way down to wearables, the info complexity will increase and so does its measurement. This knowledge is built-in into huge knowledge facilities. And the demand for sooner and higher efficiency will proceed to extend as properly. Therefore the event of excessive energy density and energy-efficient options for sensible enterprise methods have additionally develop into difficult.

Infineon Applied sciences have launched a brand new household of OptiMOS 5 IPOL buck regulators with VR14-compliant SVID normal and I²C/PMBus digital interfaces for Intel/AMD server CPUs and community ASICs/FPGAs. Measuring in a 5 x 6 mm² PQFN bundle, these gadgets are a extremely environment friendly resolution for next-generation server, storage, telecom, and datacom functions, in addition to distributed energy methods.

The OptiMOS IPOL single-voltage synchronous buck regulator TDA38640 helps as much as 40 A output present. The system is integrated with Intel SVID and I²C/PMBus digital interfaces and can be utilized for Intel VR12, VR12.5, VR13, VR14, IMPVP8 designs, and DDR reminiscence with out making any vital adjustments to the invoice of supplies (BOM).

The variants, TDA38740 and TDA38725 digital IPOL buck regulators assist as much as 40 A and 25 A output present. They arrive with a PMBus interface.  All these gadgets use Infineon’s proprietary quick fixed on time (COT) PWM engine to ship industry-leading transient efficiency whereas simplifying the design growth.

  • PWM controller and OptiMOS FETs with built-in bootstrap diode for highly-efficient energy supply.
  • Broad enter and output voltage vary
  • Programmable switching frequencies : 400 kHz to 2 MHz.
  • A number of time programming (MTP) reminiscence permits customization throughout design and high-volume manufacturing
  • Digitally programmable load line
