The UCC3580DTR-2 is a high-performance PWM controller in PMIC - AC DC Converters, Offline Switchers. It integrates the Multi-Mode Synchronous Rectifier (MMSR) to reduce the power losses in the power MOSFETs. This device is used to control non-isolated DC/DC converters with both synchronous and asynchronous rectifications for higher efficiency.

The application field of UCC3580DTR-2 includes notebook adapters, AC/DC adapters, motor drives, fly-back converters and other isolated or non-isolated applications related to DC/DC converters. It is also suitable for offline switch mode power supplies that require primary side rectification. This device few external components, which makes it ideal for low power consumption and cost-effective solutions.

The working principle of UCC3580DTR-2 is based on two integrated NE555-derivative in conjunction with a MOSFET driver. This device features a wide operating supply range of 4.5 V to 38 V and an autonomous slope compensation for constant frequency and constant on-time control (CCM). Two internal low side current sources are used for gate driving the auxiliary transistor. The PWM ramp is also provided by an externally adjustable voltage reference.

The UCC3580DTR-2 also provides PWM frequency synchronization and synchronization to an external clock. The pulse-by-pulse current limit protection settings are adjustable by one external component. The PWM dead time is controlled by a single resistor. In addition, it also offers other features such as soft start, loop compensation and external shutdown. The device is able to deliver up to 250 mA of peak gate drive current.

In summary, the UCC3580DTR-2 is a high-performance PWM controller that is suited for a broad range of applications in the AC DC Converters, Offline Switchers category, including notebook adapters, AC/DC adapters, motor drives, fly-back converters and other isolated or non-isolated solutions. It packs many features such as 4.5 to 38 V wide operating supply range, autonomous slope compensation, pulse-by-pulse current limit protection, soft start and external shutdown, etc. These features make it an excellent choice for efficient, cost-effective solutions.
