Power Management IC (PMIC) is a powerful IC used to promote efficient management of power. These ICs are used to convert AC mains or DC voltage to the required voltage levels and consume less power while performing their tasks. The ICE2A280ZXKLA1 is a Type 2/3 Hybrid Active Clamp High Efficiency Offline Switcher PMIC created by Infineon Technologies. It is designed for applications requiring AC/DC conversion with a minimum of components.

Application Field

The ICE2A280ZXKLA1 is ideally suited for applications such as:

• SMPS, EMI filter-free SMPS
• 24W mobile phone adapter and charger
• AC/DC adapter
• LED lighting solution

The ICE2A280ZXKLA1 is a compact SMPS IC, which requires only few external components to created an efficient switching power supply. Its 0.87x0.87 mm TDFN-8 package has a minimal footprint and its built-in IC control allows it to function without an external controller. Moreover, the IC can adjust its output variation based on the input voltage and current, thus providing better efficiency and stable output.

Working Principle

The ICE2A280ZXKLA1 utilizes MPU-based control for enhanced system protection. It features a 1MHz primary side PWM controller, synchronous rectification and an active clamp control on the secondary side. The IC also contains built-in protections such as over voltage protection, over current protection and over temperature protection. It has a built-in soft start for better operating efficiency.

The active clamp of ICE2A280ZXKLA1 is based on a two-stage topology that combines high efficiency with low line heard. Its primary side PWM control provides high power factor and high efficiency. The secondary side active clamp provides low noise, low EMI and low switching losses.

The ICE2A280ZXKLA1 is designed to meet the stringent requirements of SMPS. It is ideal for applications that require a tight control over the power management, while taking full advantage of the low startup cost and minimal components required. The device is also extremely efficient and offers superior operating performance.
