The Texas Instruments TPS53119RGTT is a non-synchronous buck controller for PoL (Point of Load) applications. It operates with an input voltage range from 4.5 V to 14 V and provides a regulated output voltage of 1.3 V to 3.6 V with up to 15 A of current at up to 95% efficiency. It features full internal high-side power FETs with integrated pulldown circuitry, allowing for operation without an external P-channel FET and minimising the bill of materials and design complexity. The device is easy to design using eFuses, which eliminates a system reset or supervisor circuit. Its integrated PWM (pulsewidth modulation) control provides high efficiency and low output ripple, and its internally regulated internal oscillator allows for low-cost, low-component count designs. It also features overload protection, thermal shutdown and overvoltage protection as well as soft-start and hiccup current limit features. The device is designed for applications requiring precision output voltage and low output ripple, such as ASICs, FPGAs and DSPs, as well as medical, industrial and communications systems. The TPS53119RGTT is a DC-to-DC buck switching controller that uses a pulse-width modulation (PWM) technique to control the voltage. The controller contains an integrated high-side power FET, pull-down circuitry, an oscillator, and several control logic circuits for power management and protection. The PWM generator has an adjustable dead time and can switch the output voltage with a high frequency. The controller detects and compensates for input voltage changes using its internal regulation loop and provides an adjustable soft-start, a hiccup current limit and low output ripple. The device also features an integrated overvoltage monitor and thermal shutdown features. The TPS53119RGTT is an ideal solution for applications that require a low cost and efficient buck switching controller with a high load current capability. Its features such as overload protection, thermal overload protection, soft-start and hiccup current limit make it suitable for use in low cost, high output current applications. In addition, the device\'s easy to design eFuse eliminates the need for a reset or supervisor circuit, reducing the system cost and complexity. Overall, the TPS53119RGTT is an ideal solution for efficient and low cost power management applications.The specific data is subject to PDF, and the above content is for reference
