Infineon Technologies AG has released a new family of OptiMOS 5 IPOL DC/DC regulators to meet the demand for high-power-density and energy-efficient solutions in smart enterprise solutions, such as servers, storage, telecom, and datacom applications as well as distributed power systems. The new integrated POL buck regulator family comes with VR14-compliant SVID standard and I²C/PMBus digital interfaces for Intel/AMD server CPUs and network ASICs/FPGAs.

The TDA38640 OptiMOS IPOL single-voltage synchronous buck regulator supports up to 40 A output current and comes with Intel SVID and I²C/PMBus digital interfaces. It can be used for Intel VR12, VR12.5, VR13, VR14, IMPVP8 designs and DDR memory. The TDA38740 and TDA38725 digital IPOL buck regulators support up to 40 A and 25 A output current, respectively, and come with a PMBus interface. The devices, housed in a 5 × 6 mm² PQFN package, feature Infineon’s proprietary fast constant on time (COT) PWM engine.
The synchronous buck regulators offer a small footprint solution with high efficiency thanks to their 5 × 6 mm² PQFN package as well as an onboard PWM controller and OptiMOS FETs with integrated bootstrap diode. The also offer a wide input (3 V to 17 V for all three devices) and output voltage range (0.25 V to 3.04 V for the TDA38649 and 0.25 V to 5 V for the TDA38740 and TDA38725) and programmable switching frequencies from 400 kHz to 2 MHz.
Another key feature is the multiple time programming (MTP) memory, which allows customization during design and high-volume manufacturing. Infineon said this significantly reduces design cycles and time-to-market.
The devices also offer a digitally programmable load line that can be set via configuration registers without external components, reducing bill of materials. The device configuration can be defined using Infineon’s XDP Designer GUI and is stored in the on-chip memory. The devices are available now.
