Infineon Introduces Subsequent-Technology OptiMOS Built-in POL DC-DC Regulators

As synthetic intelligence (AI) expertise is built-in into large information facilities, the demand for larger efficiency will proceed to extend. Following this pattern, excessive energy density and energy-efficient options for sensible enterprise programs have additionally turn into difficult. Because of this, Infineon Applied sciences AG  right this moment 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. Housed in a 5 x 6 mm2 PQFN package deal, these units are an easy-to-use, totally built-in, and extremely environment friendly answer for next-generation server, storage, telecom, and datacom functions, in addition to distributed energy programs.

The OptiMOS IPOL single-voltage synchronous buck regulator TDA38640 helps as much as 40 A output present. The system comes 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 vital modifications to the invoice of supplies (BOM). Infineon’s TDA38740 and TDA38725 digital IPOL buck regulators assist as much as 40 A and 25 A output present, respectively and include a PMBus interface. All three new units use Infineon’s proprietary quick fixed on time (COT) PWM engine to ship industry-leading transient efficiency whereas simplifying the design growth.

The onboard PWM controller and OptiMOS FETs with built-in bootstrap diode make these new units a small footprint answer with highly-efficient energy supply. As well as, they supply the required versatility by working in a broad enter and output voltage vary whereas providing programmable switching frequencies from 400 kHz to 2 MHz. A multiple-time programming (MTP) reminiscence permits customization throughout design and high-volume manufacturing, considerably lowering design cycles and time-to-market. In addition they supply a digitally programmable load line that may be set through configuration registers with out exterior parts, leading to a simplified BOM. The system configuration may be simply outlined utilizing Infineon’s XDP Designer GUI and is saved within the on-chip reminiscence.
