Working principle of TPS54974PWPRG4

The TPS54974PWPRG4 is a high frequency synchronous buck controller. This DC/DC regulator works by regulating the output voltage of the device via Pulse-width Modulation (PWM) of the input voltage. The device contains an internal high efficiency power switch and operates over a wide input voltage range, from 2.5V up to 5.5V. The switching frequency of this device can be programmed from 500 kHz to 6 MHz. Its maximum PWM switching frequency of 6MHz makes it suitable for a wide range of applications where high frequency operation is required.

The device contains an internal voltage regulator and can generate up to 8 PWM outputs. The PWM output signals are generated by the device’s internal PWM generator, Pulse Generator (PG) module, which has its own clock synthesizer and is independent of the main clock. Each PWM output channel can be programmed independently with its own duty cycle, frequency, slew rate and output voltage. It also has an operating temperature range up to 125°C. This makes the device suitable for high temperature applications.

The device is protected against over-voltage, over-current and over-temperature conditions. It also includes several features to enable a smooth power-up sequence such as soft start and soft-stop, low voltage lockout and over-current protection by monitoring the average current.

The TPS54974PWPRG4 provides high efficiency, precise power management, and an extended operating temperature range. This makes it suitable for a wide range of applications such as automotive, consumer electronics and medical applications. With its extensive list of features, this DC/DC switching regulator can meet most needs in terms of power conversion.
