The UC28025DWR is a high-performance, dual-channel PWM controller from Texas Instruments, specifically designed for DC-DC and offline power supply applications requiring high efficiency and precise control. It integrates two interleaved pulse-width modulation (PWM) outputs, allowing improved power conversion by reducing ripple and enhancing system reliability. The device supports a wide input voltage range and offers adjustable dead-time control, soft-start capability, and current mode operation to ensure stable and smooth startup.
The UC28025DWR operates at frequencies up to 1 MHz, making it suitable for high-frequency applications, and provides a synchronization feature for multi-phase systems. Built-in protection features, such as over-current, under-voltage lockout (UVLO), and thermal shutdown, further enhance system safety. Packaged in a 16-pin SOIC, it is ideal for applications like telecom power supplies, industrial converters, and server power management.
