The LM2585SX-3.3 is a monolithic integrated circuit designed for use in flyback, step-up (boost), and forward converter applications. It provides a fixed output voltage of 3.3V and can deliver up to 3A of output current. The device operates within a wide input voltage range of 4V to 40V, making it versatile for various applications. This regulator features current-mode operation, which enhances transient response and line regulation. It includes built-in protections such as current limiting, thermal shutdown, and undervoltage lockout, ensuring reliable operation. The internal oscillator operates at a fixed frequency of 100 kHz, allowing for the use of smaller magnetic components. The LM2585SX-3.3 is designed to require minimal external components, simplifying the design process. It guarantees an output voltage tolerance of ±4% under specified conditions, making it suitable for applications where precise voltage regulation is critical. Typical applications include flyback regulators, multiple-output regulators, and simple boost regulators.
