The UCC2810N is a versatile and robust PWM (Pulse Width Modulation) controller from Texas Instruments designed for a wide range of power supply applications. Built using advanced BiCMOS technology, this controller offers an optimal balance between power consumption and performance, making it suitable for both battery-operated and AC-powered systems.

Key Features

• Current-Mode Control: Provides fast response to load changes and inherent protection against short circuits, enhancing overall system reliability.
• Low Startup and Operating Current: The device features a low startup current of typically 0.5µA and an operating current of 2.5mA, making it ideal for power-efficient designs.
• Trimmed Oscillator Discharge Current: Ensures precise duty cycle clamping which is critical for the protection and control of the power stage.
• Under-Voltage Lockout (UVLO): Both startup and operating UVLO thresholds are included to ensure the controller starts up and operates only when the supply voltage is sufficient.
• High Current Totem-Pole Output: Capable of directly driving a power MOSFET, the output stage features a high current totem-pole configuration that is capable of sourcing and sinking over 1A of current.

Applications

The UCC2810N is designed for a variety of applications, including:

• DC to DC converters
• Offline power supplies
• AC-DC adapters and chargers
• Telecommunication power supplies
• Industrial power systems
