The TPS40180RGER is a high-performance integrated power stage controller designed to generate the highest efficiency in a DC-DC buck converter applications. It provides the user a wide range of Features and performance characteristics to ensure full system optimization, while providing a high level of functionality.

The TPS40180RGER has a variety of operating modes including constant voltage (CV), constant current(CC) and PWM control modes. In CV mode, the converter operates in a fixed voltage mode, and the output is regulated with respect to the reference voltage. In CC mode, the converter operates in a constant current mode and the output is regulated to the reference current. PWM control mode allows the converter to operate in a pulse width modulation (PWM) mode and provides a more accurate regulation of the output voltage over temperature and load changes.

The TPS40180RGER also offers the user different switching frequencies, ranging from 300 kHz to 3 MHz, allowing for efficient system designs. The wide input voltage range of 6 V to 28 V and the wide output voltage range of 0.8 V up to 26 V allows the user to obtain the optimized output power from the converter.Another key feature of the device is the integrated gate drivers that drive the two power MOSFETs which makes the implementation of power stages easier and reduces the external components count.

The TPS40180RGER is an ideal solution for many DC-DC buck converter applications such as processor core voltage, notebook PC, PC systems, LCD monitors, LED driver and industrial systems. It is available in several packages, to suit different customer design needs, and offers very low on-resistance with low coil inductance up to 0.8 mH. In addition, the device provides very low steady-state and dynamic output voltage ripple, making it the ideal choice for applications that require high efficiency and smooth regulation.

The TPS40180RGER also offers ultrasonic mode switching to reduce the acoustic noise typically present in high frequency switching power supplies. In addition to these features, the device offers many safety and protection features such as over temperature protection (OTP), undervoltage lockout (UVLO) and over current protection (OCP). It also provides adjustable slope compensation that allows the user to tune the frequency and improve transient response and system stability.

In conclusion, the TPS40180RGER is an ideal choice for any application requiring low power conversion in buck topologies. It features a wide voltage range, high power efficiency, and offers several protection features to ensure reliable and safe operation. Its integrated gate drivers help reduce component count and keep the converter small, making it ideal for space constrained applications.
