Product Overview: Texas Instruments UCC3813PW-4

The UCC3813PW-4 from Texas Instruments is a high-performance, fixed-frequency current mode PWM controller. This integrated circuit is designed to provide reliable and efficient power management solutions for a wide range of applications, including switch-mode power supplies, DC-DC converters, and other power control systems.

Key Features

• Operating Frequency: The UCC3813PW-4 operates at a fixed frequency of 1MHz, which enables the design of power supplies with smaller components, resulting in compact and lightweight solutions.
• Peak Current Mode Control: This method of control simplifies loop compensation, improves transient response, and allows for excellent line and load regulation.
• Low Startup and Operating Current: The device features a low startup current of typically 0.5 mA and an operating current of typically 2.5 mA, which enhances the overall efficiency of the power supply.
• High Current Totem Pole Output: The output driver is capable of driving a high current totem pole, which allows for direct driving of the power MOSFET.
• Wide Input Voltage Range: It is designed to accommodate a broad input voltage range, making it versatile for various applications.
• Undervoltage Lockout (UVLO): The UVLO feature ensures that the device remains off unless the supply voltage is sufficient to maintain proper operation, protecting the circuit from low voltage conditions.
• Programmable Soft Start: This feature limits inrush current during startup, which contributes to the reliability and longevity of the power supply.
