The UCC2807D-1G4 is a sophisticated pulse width modulation (PWM) controller from Texas Instruments, designed to cater to a wide variety of power conversion applications. This device is part of the UCC2807x family, which is known for its low-power operation and flexible features that make it suitable for designing high-efficiency power supplies.

Key Features

• Frequency Range: The UCC2807D-1G4 operates at a fixed frequency that can be programmed by the user with a single external resistor. This allows for precise control over the switching frequency to optimize for efficiency or to avoid critical noise-sensitive frequency bands.
• Low Startup Current: This controller boasts a startup current of typically 100 µA, which is ideal for battery-powered and energy-efficient applications where every microampere counts.
• Trimmed Oscillator Discharge Current: The discharge current is well controlled and trimmed to ensure consistent frequency accuracy and repeatability from unit to unit, which is critical for applications requiring precise power regulation.
• Peak Current Mode Control: The UCC2807D-1G4 employs peak current mode control, which provides inherent cycle-by-cycle current limiting and easy loop compensation.
• Drive Capability: It is capable of directly driving a power MOSFET, simplifying the design by eliminating the need for additional driver components.

Applications

The versatile nature of the UCC2807D-1G4 makes it suitable for a broad range of power supply designs, including:

• DC-DC Converters
• Offline Power Supplies
• Telecom and Datacom Power Systems
