UC28025DWR General Description

The UC28025DWR is an integrated circuit (IC) manufactured by Texas Instruments. It belongs to the UC28025 family of synchronous buck controllers. This IC is designed for high-efficiency step-down (buck) DC-DC converter applications. It operates with a wide input voltage range, typically from 4.5V to 28V, making it suitable for various power supply designs. The UC28025DWR features a fixed frequency PWM control scheme, which helps in achieving stable and predictable output voltage regulation. It offers adjustable output voltage and current limiting functions, allowing flexibility in power supply configurations. With built-in protection features such as overcurrent protection, thermal shutdown, and under-voltage lockout, the UC28025DWR ensures reliable operation and safeguards against potential hazards. This IC comes in a small outline package (SOIC) with thermal pad for enhanced thermal performance.
