Application Field

The ICE5AR0680AGXUMA1 is designed to provide high-efficiency, low-cost solutions for multi-phase AC-DC, DC-DC and DC-AC converters. It is ideal for applications such as desktop PC, networking, and home appliances, where peak efficiency, low standby power and EMI requirements must be met. In addition, it is suitable for automotive, industrial, medical and avionics applications, allowing flexible system architecture to meet the requirements of various international standards.

Working Principle

At the core of the ICE5AR0680AGXUMA1 is a multi-phase power (MPP) topology, which is designed to effectively reduce system power losses and provide high efficiency. In MPP topologies, multiple power switches are used in parallel to provide a higher power output. This increases the system\'s efficiency by maintaining a higher load current while simultaneously decreasing the power loss per switch.

The ICE5AR0680AGXUMA1 uses an advanced driver IC to control the power switches, ensuring a fast and accurate power cycling process. It employs a high-voltage gate switch to shut off the current and reduce the voltage stress of the switches. Furthermore, it employs a hysteretic output current sensing technique to provide fast current limit protection, resulting in reduced power losses and improved system efficiency.

The ICE5AR0680AGXUMA1 supports fixed-frequency and variable-frequency modes, allowing for a flexible and efficient design of power supplies. Fixed-frequency mode offers high efficiency, light load efficiency and fast transient response. The variable-frequency mode, on the other hand, allows for improved system energy savings. In addition, it features fast slope control and stability feedback compensation to provide superior system loads and output voltage control.
