The ICE3B2065JXKLA1 is a fully integrated Secondary Side Pulse Width Modulation Controller with a prefix IC power device. It is one of the latest members of Infineon’s family of AC/DC converters, offline switchers, and power supply controllers. These types of devices are found in almost every sector of the power electronics industry, ranging from everyday home appliances to large scale industrial applications. The ICE3B2065JXKLA1 is well suited for offline power supplies and other non-isolated topologies where high efficiency, maximum power and noise reduction are required.

The ICE3B2065JXKLA1 features a gate drive current of up to 8A, which is significantly higher than similar devices from competing manufactures, thus providing an improved power output and higher efficiency. This makes the device an ideal choice when fast power up times, high power and efficiency are desired. Additionally, the device includes a number of integrated protection and fault detection features, such as overvoltage, overcurrent and overtemperature protection. This helps to keep the system both safe and reliable during different operating conditions.

The primary function of the ICE3B2065JXKLA1 is to provide pulse width modulation (PWM) control for the gate driver of a secondary side power switch. PWM is an important control mechanism of power devices, and is used to change the average power output of an electrical system by constantly and rapidly pulsing the output signal on and off. By controlling the pulse width, the system can be made to run at the desired operation frequency and output power. The ICE3B2065JXKLA1 provides this functionality with a maximum frequency of 1MHz and a total over-current threshold of 3A.

The ICE3B2065JXKLA1 also features a number of integrated features that help simplify the development and optimization of offline power supplies and other non-isolated topologies. These features include a pre-bias start up detection and a brown-in detection mode. The pre-bias start-up detection ensures that the device will initiating a power-up cycle even when a low-voltage or pre-biased AC line is present, while the latter aids in providing a longer and more reliable operation of the device. In addition, the ICE3B2065JXKLA1 also features an integrated switching frequency synchronization, which helps reduce EMI and is especially beneficial in single-stage topologies.

The ICE3B2065JXKLA1 also includes a variety of integrated safety functions and fault protections. This includes over temperature, over current and overvoltage flags, as well as an integrated over-voltage lockout circuit and a blanking circuit. All of these functions help to improve system reliability and reduce risks of improper operation. Finally, the device also has active power factor correction (APFC) and resonant-mode synchronous rectification control capabilities.

The ICE3B2065JXKLA1 is a highly integrated and cost-effective solution for PMIC AC/DC converters, offline switchers, and power supply controllers. It provides fast power-up, high efficiency, and excellent noise reduction. Furthermore, the integrated safety features and fault protection improve system reliability, while the various integrated features simplify development and reduce the overall system cost. As such, the ICE3B2065JXKLA1 is a great choice when looking for a PWM controller for any such PMIC application.
