The device consists of a current-mode, hysteretic-control PWM regulator combined with an adaptive voltage regulator (AVR), both operating at the same switching frequency. In this article, we will discuss the application fields and working principle of the TPS63024YFFR.

The TPS63024YFFR enables efficient conversion of input voltage to a variety of adjustable output voltages. The device has a wide input voltage range (3.3V to 14V) and a maximum output voltage of 25V. The AVR mode allows the device to efficiently operate in light load conditions and provides improved line and load regulation. It also has a programmable soft start to reduce current surge and to reduce switch-on stress. The adjustable switching frequency allows the converter to be optimized for high performance and/or low EMI. The TPS63024YFFR is suitable for a variety of portable applications such as LTE or 5G power amplifiers, Bluetooth amplifiers, mobile phone transmitters, receivers, computer graphics, and hard drive supplies. It offers excellent power efficiency, low quiescent current, and low standby power.

The TPS63024YFFR consists of a current-mode, hysteretic-control PWM regulator that operates in current mode at constant frequency and an adaptive voltage regulator (AVR) that uses an external capacitor to control the output voltage. The PWM regulator consists of an error amplifier, a voltage reference, an internal oscillator, a gate driver, an external N-channel MOSFET switch, an inductor, and a diode. The AVR consists of a voltage reference, an error amplifier, an external capacitor and a voltage divider. The PWM regulator senses the output voltage through the voltage divider and adjusts the switching frequency to maintain the output voltage.#The PWM regulator and AVR operate at the same switching frequency. The PWM regulator adjusts the switching frequency of the external N-channel MOSFET switch to maintain the desired output voltage. The inductor is used to store and release energy to the output when the MOSFET switch is switched on and off respectively. The diode conducts when the MOSFET switch is off, allowing the inductor to discharge its energy. The AVR senses the output voltage and adjusts the duty cycle of the PWM regulator in order to maintain the desired output voltage.

Overall, the TPS63024YFFR is an excellent choice for a variety of portable applications due to its wide input voltage range, excellent load and line regulation, programmable soft start, adjustable switching frequency, and excellent power efficiency. It offers flexibility and optimized performance, making it a reliable and cost-effective solution.
