TPS82675SIPT – TEXAS INSTRUMENTS

The TPS82675SIPT is a 5A synchronous step-down converter from Texas Instruments, packaged in a space-saving 6-pin SOT-23-6 (SIP) package. It operates from a wide input voltage range of 2.7V to 5.5V, efficiently generating a regulated output voltage adjustable from 0.8V to 5V via external resistor divider. This device features a high switching frequency of up to 2.2MHz, minimizing the size of external components and enabling efficient operation in space-constrained applications. Its internal synchronous rectification improves efficiency, typically achieving >90% efficiency at light to moderate loads._x000D_

The TPS82675SIPT incorporates features crucial for robust operation, including adjustable soft-start, overcurrent protection, thermal shutdown, and undervoltage lockout. Its small size and high efficiency make it ideal for portable devices, particularly those with multiple voltage rails requiring high current density and minimal board space. Common use cases include powering microprocessors, memory chips, and other high-current digital logic within smartphones, wearables, and other battery-powered systems where efficient power conversion is paramount. The device’s integrated protection mechanisms contribute to enhanced system reliability. Designers should note the need for careful selection of external components to optimize performance within the specified operating conditions.
