TPS62865RQYR – TEXAS INSTRUMENTS

The TPS62865RQYR is a highly integrated, 400mA synchronous step-down converter from Texas Instruments, packaged in a compact 6-pin WSON (WCSP-6) package. It operates from a wide input voltage range of 2.7V to 5.5V, generating a precisely regulated output voltage, adjustable from 0.8V to 5.0V via an external resistor divider. Key features include a switching frequency of 1.2MHz, enabling the use of smaller, less expensive external components. Its internal 400mA switch current and high efficiency (up to 95%) make it suitable for applications requiring relatively high current output with minimal power loss. The device incorporates features like soft-start, enabling controlled inrush current limiting, and overcurrent protection, ensuring robust operation. Typical use cases include powering high-performance microprocessors, memory chips, and other high-current digital logic in portable devices where space and efficiency are critical. The TPS62865RQYR’s advantages lie in its small size, high efficiency, and integrated protection features, simplifying design and improving overall system performance compared to discrete solutions or less integrated converters. Its fixed switching frequency simplifies EMI filtering design.
