The TL598CD from Texas Instruments is a versatile Pulse-Width-Modulation (PWM) control circuit designed to offer flexible and precise control for a wide array of power supply and conversion applications. This integrated circuit (IC) is engineered to simplify the design of complex power supplies by integrating multiple functions within a single chip.

Key Features:

• Dual PWM Outputs: The TL598CD features two PWM outputs that can be used independently or in sync, allowing for dual control in push-pull, half-bridge, or full-bridge configurations.
• Adjustable Dead-Time Control: Designers can adjust the dead time between the two outputs, optimizing efficiency and preventing cross-conduction in power stages.
• Wide Operating Frequency Range: The device supports a broad range of switching frequencies, making it suitable for various applications from DC-DC converters to motor control.
• Voltage Control Oscillator (VCO): The onboard VCO allows frequency modulation for improved electromagnetic compatibility (EMC) performance.
• Error Amplifier: An integrated error amplifier provides closed-loop feedback for voltage or current regulation, enhancing the performance of the power supply.
• Under-Voltage Lockout (UVLO): The UVLO feature ensures that the device operates only when the supply voltage is within an acceptable range, protecting the circuitry.
