The TPS51225RUKT from Texas Instruments is a cost-effective, dual-synchronous buck controller designed for notebook system-power supply solutions. It integrates two buck controllers and two 5-V and 3.3-V LDOs, requiring minimal external components for operation.
This controller features a wide input voltage range of 5.5 V to 24 V, making it suitable for various power management applications. It operates within a temperature range of -40°C to 85°C. The device utilizes an adaptive on-time D-CAP mode control architecture with selectable switching frequencies of 300 kHz or 355 kHz.
Key electrical characteristics include built-in 100-mA LDOs, ±1% reference accuracy, and low-side R DS(on) current sensing. It also incorporates features like auto-skip light load operation, internal soft-start, and output discharge functionality. Protection features include OVP/UVP/OCP and non-latch UVLO/OTP.
The TPS51225RUKT is available in a 20-pin WQFN package measuring 3 mm x 3 mm, designed for surface mount applications.
