The UCC28083D, manufactured by Texas Instruments, is a high-performance, dual-output, push-pull PWM controller designed for DC-DC conversion applications. This integrated circuit is engineered to provide efficient power management and is particularly suitable for use in off-line and DC-to-DC converter configurations.

Key Features

• Advanced PWM Control: The UCC28083D features a fixed-frequency, current-mode control scheme that allows for stable and efficient operation across a wide range of input voltages and output loads.
• Wide Supply Voltage Range: It operates over a supply voltage range of 10 V to 15 V, making it versatile for various system designs.
• Dual Output Drive Stages: The dual output drive stages can sink and source high peak current, providing robust drive capability for power MOSFETs.
• Internal Soft Start: An internal soft-start function limits inrush current during startup, enhancing system reliability.
• Frequency Synchronization: It offers the ability to synchronize the switching frequency with an external clock, enabling noise-sensitive applications to minimize electromagnetic interference (EMI).
• Low Startup and Operating Current: The UCC28083D is designed to consume low startup current and has a low operating current, which contributes to the overall efficiency of the power supply.
• Overcurrent Protection: Built-in overcurrent protection helps prevent damage to the IC and the power system under extreme conditions.
