TPS546C23RVFT is an integrated switching regulator that allows for easy step-down DC/DC conversion from 20V to 0.6V. It features integrated high-side and low-side power MOSFETs and a configurable valley current limit for constant on-time (COT) control. It also provides light load efficiency and low-quiescent current of only 9.2mA.

The TPS546C23RVFT is optimized for high-efficiency and high-density applications that are typically found in embedded systems and data centers. It features integrated switching current limit and peak current limit, both of which help optimize overall system power efficiency and reduce component count. In addition, the TPS546C23RVFT has an adjustable soft-start, reverse current protection, and an internal power switch (PSW) with adjustable slew rate.

The TPS546C23RVFT can provide a wide range of output voltages with a good load transient response, while still providing good efficiency. Its ultra-low internal start-up current and other advanced features also allow for stable operation and improved power system reliability.

The application field and working principle of the TPS546C23RVFT can be seen in its names, which stands for Current Mode Step-Down Integrated Switch Regulator with a maximum input voltage of 20V and a max output voltage of 0.6V. When the voltage on the input of the device (VIN) exceeds the output (VOUT), an internal power switch is engaged and a current is directed through an inductor. This creates a magnetic field, which stores energy. When the voltage at the output (VOUT) starts to fall, the internal power switch is disabled, allowing the inductor to release energy, which is then converted to the desired voltage level.

The switching frequency on the TPS546C23RVFT can be adjusted via an external resistor, allowing users to adjust the frequency to suit the application. It also features spread spectrum operation which helps reduce the electromagnetic interference (EMI). The current limit can also be adjusted to suit the applications’ current requirements, and it also features an adjustable soft-start to reduce inrush current.

The TPS546C23RVFT also provides a wide operating temperature range and high transient response, making it well suited to a wide range of applications. It is ideal for energy-efficient power supplies, automotive engine management, computing, telecom and consumer electronics applications, and many more.

In conclusion, the TPS546C23RVFT is a versatile integrated switching regulator that provides high-efficiency DC/DC conversions from 20V to 0.6V. It features a wide range of features, including adjustable switching frequency, current limit, soft-start and reverse current protection. This device is ideal for applications that require high efficiency and low power consumption at a wide range of temperatures.
