The TPS2400DBVRG4 is a programmable precision current-mode switching regulator controller manufactured by Texas Instruments. It is a power management integrated circuit (PMIC) designed to improve system efficiency, reduce form factor and reduce cost. The device offers a fully integrated, efficient and easy-to-use power supply design solution. It integrates a wide range of features, including a high and lowside switch, adjustable current control, PWM and Slew Rate Control, and adjustable switching frequencies. This versatile device is suitable for many applications and can be programmed to provide a custom power management solution.

The TPS2400DBVRG4 is part of Texas Instruments\' Power Supply Controllers, Monitors product longevity family, which specifies that its minimum owner-identifiable lifetime is 13 years from date of introduction. This durable device can reduce system cost by eliminating the need to replace it or its components over time.

The TPS2400DBVRG4 has a wide range of application fields, such as point-of-load (POL) system, PC related system, and portable equipment. In terms of board level design, the TPS2400DBVRG4 gives the board designer the ability to implement a complete power solution in a small footprint.

The TPS2400DBVRG4 works based on current mode control and adjustable frequency control, designed to support a range of power supply systems from medium to large loads. The device operates from an adjustable frequency range of 200kHz to 500kHz with a low-side MOSFET switch and high-side MOSFET switch. The device also features an external Soft-Start and a PWM/Slew Rate Control (SRC) output.

The main function of the Soft-Start feature is to limit inrush current during power-up and to ensure a smooth start-up of the system. It also prevents overshoot and undershoot of output voltage when transitioning from switching to light load in the load step. The Soft-Start feature consists of an external capacitor connected to the Soft-Start pin.

The PWM/Slew Rate Control output provides the designer the ability to control the output voltage during load transient and light load conditions. The PWM/Slew Rate Control output can be programmed to provide two levels of response depending on the output voltage during transient conditions. This provides the system designer the ability to control the dynamic performance of the power supply depending on the external design.

The TPS2400DBVRG4 also features adjustable current control, overload protection and overvoltage protection which protect the system from damage due to current overload, excessive voltage, and open loop failure. The device also features thermal shutdown protection which shuts down the device to protect it from damage due to over-temperature conditions.

In conclusion, the TPS2400DBVRG4 is a versatile power management integrated circuit suitable for a wide range of applications. It is part of Texas Instruments\' Power Supply Controllers, Monitors product longevity family and offers a long life span of up to 13 years. The device provides a variety of features such as current-mode control, adjustable frequency control, adjustable current control, PWM/Slew Rate Control, and overload protection which help designers create cost-effective and efficient power supply systems.
