Integrated POL Voltage Regulators

Highest density high efficiency integrated POL (IPOL) for smart enterprise systems

Infineon’s Integrated POL switching converters deliver benchmark efficiency and dramatically reduce system size. Solutions up to 35 A are available in compact PQFN packages. Target applications include server, storage, routers and switches, telecom base stations, digital home media, mobile computing and embedded data processing. Solutions with and without PMBus digital communication are available in single output and multi-rail format.

Ready-to-go reference designs and the on-line PowerDesk simulator simplify the task of designing regulated voltage rails. Different control topologies are available to meet an application’s specific requirements. Use the table below to select the most appropriate topology.

Integrated POL Digital Interface

The digital interface IPOL devices are easy-to-use, fully integrated and highly efficient D-DC regulator offering I2C/PMBus, Parallel VID, Intel SVID. The on-board PWM controller and MOSFETs make the family a space efficient solution, providing accurate power delivery for low output voltage and high current applications.

The IR3806x family of PMBus enabled voltage regulators offers:

• Compactness of integrated controller, driver and MOSFETs
• High performance analog voltage mode engine
• Flexibility of a rich PMBus interface

The IR381(2/3)6x family features OptiMOS™5 for the highest efficiency and adds Intel SVID support (IR381(/3)6x) for Intel based systems or Parallel VID (IR3826x) for voltage scaling or 8 programmable output voltages booting options to avoid programming at start up. Pin compatible options with and without PMBUS are available to allow the flexibility of using PMBUS only during evaluation or easily upgrade a system to PMBUS without re-layout.

Integrated POL Analog Voltage Regulators (Industrial)

High efficiency and accuracy

Our point-of-load converters integrate a PWM controller, driver and MOSFETs into a small PQFN package for ease-of-use. The patented PWM modulation scheme allows greater than 1 MHz switching frequencies to deliver ultra compact layouts and smallest bill-of-materials. Wide operating temperature from -40° to 125°C.

Main Benefits

• Enhanced Voltage Mode PWM devices offer high accuracy, ultra-low ripple and noise, and higher control bandwidth for less capacitors.
• Scalable solution from 3A up to 35A.
• For designs requiring high density, low cost and easy design, the family includes a 3A device with Enhanced Stability Constant-on-Time engine that does not require external compensation enabling easy designs and fast time to market.
