ICE2QR0665GXUMA1 Integrated Circuits (ICs)

The ICE2QR0665GXUMA1 integrated circuit (IC) is a part of PICMG (PCI Industrial Computer Manufacturers\' Group) AC DC Converters, Offline Switchers. The main purpose of this IC is to provide a switch mode power supply with a high and precise output voltage in order to guarantee the quality of the product that it is incorporated into.

The application field of ICE2QR0665GXUMA1 is mainly related to the development of power supplies and devices that require high isola- tion between the primary and the secondary circuits. This IC is perfect for those electronic applications that demand a reliable power supply and require a high voltage quality.

In terms of its working principle, ICE2QR0665GXUMA1 is based on a half-bridge LLC weak-link resonant converter method, which is also known as "hill-climbing". This topology is a cost-effective solution for providing high and precise output volt- ages in a switch mode power supply.

The IC uses this topology to provide a direct and isolated DC/AC signal conversion, or a direct DC to DC conversion. The AC signal is first isolated through an isolation transformer, then rectified and again separated, resulting in a low-noise, high-efficiency output current.

Furthermore, the IC integrated a digital control IC in order to guarantee an optimized and accurate operation of the system. The digital control IC consists of a simple I/O structure that can be easily set up in the target system. This consists of an input voltage feedback loop with an accurate voltage reading, a temperature sensor and a clock in order to guarantee the accuracy of the system.

The IC also has two internal control loops, one for the pulse width modulation (PWM) and one for the over-current protection in order to guarantee a stable performance in terms of the output voltage.

Finally, the IC provides an on/off signal that can be used to control the power supply’s operation mode. This signal is used by the system to switch between the normal operation mode and the lower standby mode in order to reduce power consumption.

In a nutshell, the ICE2QR0665GXUMA1 is an AC DC converter and offline switcher that provides a cost-effective solution for providing high and precise output voltage. Its main application fields include the development of power supplies and devices that demand a reliable power supply and require a high voltage quality. It works with a digital control IC and efficient internal control loops in order to guarantee a stable and accurate performance.
