Taiwan Semiconductor Co., Ltd. DC DC Switching Controllers TS2509CS RLG

The TS2509CS RLG is a step-down switching regulator designed for efficient power conversion in portable devices. It operates with an input voltage range of 3.6V to 23V and can output voltages from 0.8V to Vcc. The device features a PWM control with a duty ratio of 0% to 100% and an oscillation frequency of approximately 500kHz. Key functionalities include soft-start, current limit, enable function, thermal shutdown, and short circuit protection, which enhance its reliability and performance. The regulator can deliver up to 3A of output current and is optimized for low-ripple power and high efficiency, making it suitable for applications requiring stable voltage regulation. The internal PMOS switch and built-in compensation circuit minimize the need for external components, simplifying design efforts. The TS2509CS RLG is packaged in an SOP-8 format, facilitating integration into various electronic systems.
