OPTIREG™ switcher

High-quality switching regulators for automotive ECU designs

Automotive environments can prove to be a challenge for standard voltage regulators. Varying temperature levels, constant input transients, and general interference can make for a tough and inconsistent operative environment. Infineon OPTIREG™ automotive switching regulators are designed to withstand harsh automotive environments. They offer a broad range of integrated protection and control features to ensure efficient, high-quality automotive electronic control units (ECUs). Switching regulators can be used to generate a single stabilized output voltage from a number of different input voltages. They are low-quiescent and can utilize over 95% of electricity converted in most cases, resulting in very little energy waste. This makes switching regulators not only highly efficient but also the cost-effective choice for customers looking for quality and flexibility in automotive ECU design. 

Robust and efficient: OPTIREG™ automotive switching regulators

OPTIREG™ automotive switching regulators from Infineon offer a high level of product robustness and quality to ensure efficient operation across a wide range of automotive applications. Switching regulators are DC/DC converters that can convert an unregulated input direct current into a stabilized output direct current of a different voltage. This is possible because of a number of inbuilt protection features that are optimized for current regulation and limitations, such as overvoltage/undervoltage monitoring, wide switching frequency, and integrated high- and low-side power MOSFETs.

OPTIREG™ switchers utilize a wide input voltage range as well as a flexible switching frequency range and come in different converter types, including buck converters (step down), boost converters (step up), and automotive buck-boost converters. Our green automotive switching regulators are RoHS-compliant and meet global standards for environmental safety.

Automotive switchers designed for use in harsh environments

OPTIREG™ automotive switchers are designed to be robust and highly efficient, which makes them ideally suited for use in harsher climates. Their other features include a wide input range, current and voltage regulation, a flexible switching range, and overvoltage/undervoltage protection. The OPTIREG™ family includes a diverse selection of automotive buck, boost, and buck-boost converters that offer low-energy consumption. Additionally, all OPTIREG™ green products are RoHS-compliant.

Our portfolio includes buck, boost, & buck-boost switching regulators

OPTIREG™ product family of automotive switching regulators are specially designed for harsh automotive environments. There are three different types of automotive switchers which can be used for the effective design of ECUs, depending on the desired customer application. These include buck converters (also known as step-down converters), which convert a high input direct current into a low output direct current of the same polarity, boost converters (also known as step-up converters), which convert a low input direct current into a high output direct current of the same polarity, and buck-boost converters (also known as a step-up/step-down converter), which convert an input direct current into an output direct current of a higher or lower voltage, or a voltage of inverted polarity.

Switching regulators designed for a range of automotive applications

OPTIREG™ product series can be used for a variety of automotive applications and are particularly suited to applications with higher microcontroller demand and multiple digital loads, such as ADAS, telematics, gateway, display, and cluster. They are also compatible with traditional automotive applications where high efficiency and solution sizes are important. Infineon switching regulators are optimized for reliable, long-term performance and offer a robust and compact design, making them suitable for harsh environments. Our green industrial switching regulators are RoHS-compliant and meet global standards for environmental safety.
