The Texas Instruments TPS5140PAG is a versatile four-channel DC/DC controller chip designed to power the voltage rails required by notebook peripheral components. It integrates three independent step-down DC/DC controllers and one 12-V boost DC/DC converter onto a single chip.
Key electrical specifications include an input voltage range of 4.5 V to 28 V. The step-down controllers offer adjustable output voltages down to 1.2 V. The device utilizes synchronous-buck operation for high efficiency and features auto PWM/SKIP mode to optimize efficiency under various load conditions. It also includes separate standby control and over-current protection for each channel, along with over-voltage and under-voltage protection.
The TPS5140PAG operates within a temperature range of -20°C to 85°C. It is housed in a 64-TQFP package, suitable for surface mount applications. The controller is designed for notebook power systems, providing a robust solution for managing multiple voltage rails.
This controller simplifies system design with features like resistorless current protection and fixed high-side driver voltage, reducing the external component count. Its architecture supports efficient power delivery for demanding notebook applications.
