The UCC2808ADTR-1G4 is a state-of-the-art low-power, high-performance, BiCMOS current-mode pulse-width modulation (PWM) controller from Texas Instruments. Designed for a wide range of power supply applications, this controller is particularly well-suited for use in off-line and DC-to-DC converter configurations. Its advanced features and compact design make it an ideal choice for engineers looking to optimize power management in their electronic designs.

Key Features

• Low Startup and Operating Current: The device boasts an ultra-low startup current of 0.5 µA and a low operating current of 2.5 mA, which significantly enhances the efficiency of the power supply and reduces standby power consumption.
• High-Frequency Operation: Capable of operating at frequencies up to 1 MHz, the UCC2808ADTR-1G4 allows for smaller external components, reducing the overall size and cost of the power supply.
• Trimmed Oscillator Discharge Current: The oscillator discharge current is trimmed to ensure precise duty cycle clamping, which helps to protect the power stage components from stress during overload conditions.
• Current Mode Control: The current mode control provides inherent line feed-forward, cycle-by-cycle current limiting, and ease of loop compensation.

Applications

• AC-DC Converters
• Isolated and Non-Isolated Power Supplies
• Telecom and Datacom Power
• DC-DC Modules
• Portable and Battery-Powered Equipment

Quality and Reliability

As with all Texas Instruments products, the UCC2808ADTR-1G4 is manufactured to the highest quality standards. It is available in a thin shrink small-outline package (TSSOP), which is ideal for space-constrained applications. The device also features overcurrent protection and thermal shutdown for enhanced reliability and longevity of the product.

Environmental Compliance

The UCC2808ADTR-1G4 is compliant with RoHS and Green Product requirements, reflecting Texas Instruments' commitment to environmental sustainability. Its lead-free and halogen-free design ensures that it meets global regulations for electronic products.
