The TPS40197RGYR DC-DC Switching Controllers are a family of integrated power switches tailored to power supply systems. The family offers both single-output and multiple-output solutions for applications requiring the highest levels of performance, efficiency, and reliability. The controllers are available in a wide range of configurations and are designed to operate with a wide range of input and output voltages.

The TPS40197RGYR devices are designed to operate in two or more power supply systems, such as a buck-boost or flyback, by incorporating a steady state control system to maintain current and voltage within an acceptable operating range. The devices also feature a slew-rate control system to optimize efficiency and minimize power dissipation during transitions.

The TPS40197RGYR DC-DC switching controllers feature a wide range of functional blocks that are appropriate for various power supply systems, including high-side and low-side MOSFETs, operational amplifiers, voltage feedback loops and regulators, soft start, and over-voltage protection. The devices also include a variety of protection features, such as thermal shutdown and current over-protection, and a choice of error signalling.

The TPS40197RGYR DC-DC switching controllers are ideal for applications that require a precise control of output voltage and precise regulation of the load current. Such applications include automotive, avionics, and industrial control.

The TPS40197RGYR devices use two “sensing” nodes (VCOMP and ILIM) to monitor the output voltage and the load current, respectively. The ILIM pin is connected to the load current measuring circuit, which senses the load current and provides a current limit (CL) signal to the TPS40197RGYR. The VCOMP pin is connected to the output voltage sensing circuit, which senses the output voltage and provides the error signal (E) and the switching frequency (FSW) to the TPS40197RGYR.

The TPS40197RGYR DC-DC switching controllers feature a PWM generator, which converts the E and FSW signals into a carrier with the desired frequency and duty cycle. The PWM generator then drives the MOSFETs in the switching circuit to modulate the input voltage into the desired output voltage level. The controllers also feature an optional soft-start circuit, which allows the voltage output to slowly ramp up after start-up to reduce any in-rush current. Additionally, the controllers include an overvoltage protection circuit that will disable the controller when the output voltage exceeds a certain predefined threshold.

Apart from the above functional blocks, the TPS40197RGYR also comes with an internal oscillator, which provides a stable clock signal for the PWM generator. Moreover, the controllers also feature a low-power sleep mode, which can be further enhanced by the use of an external MOSFET to switch off the power supply when the system is in a low-power state.

Overall, the TPS40197RGYR are highly integrated and versatile DC-DC switching controllers that are suitable for many applications. They can operate at both high and low output voltages, and can provide consistent and stable output current in both continuous and pulse mode. The controllers have robust protection features, such as overvoltage protection, thermal shutdown, and current over-protection, and can offer both single-output and multiple-output solutions. The controllers are ideal for applications that require precise control of output voltage and precise regulation of the load current.
