TPS60123PWPR Application Field and Working Principle

The TPS60123PWPR DC-DC converter is a power management integrated circuit (PMIC) designed to regulate voltage in modern electronic systems. This device, part of the DC-DC Switching Regulators family, utilizes a high-side switch, a low-side synchronous rectifier and an integrated level shifter to ensure seamless overall system power delivery and voltage regulation. The high power conversion efficiency, great dynamic response, integrated safety features and multiple operating modes make the TPS60123PWPR popular and suitable for a variety of power-requiring applications.

Among the many applications of the TPS60123PWPR, the DC-DC converter is employed for regulating and controlling power of core units such as microprocessors, memory and FPGAs in laptop and desktop computers, set-top boxes, gaming devices, TVs, and embedded systems. The boost converter can also be used for inducing inrush current and voltage stabilization for power-requiring load. Moreover, the TPS60123PWPR can be used to provide a steady low supply voltage to external devices when wired in tandem with a low dropout regulator.

The TPS60123PWPR DC-DC Switched Mode Converter works on a features-packed control loop. With fast-paced control, the boost converter uses Pulse Width Modulation (PWM) to control the output voltage of the power flow and synchronous rectifier to minimize the power dissipation of voltage regulator. It can also be set to variable frequency operation mode, autonomously adjusting the output frequency based on the output load. When set in PWM mode, the device switches an internal MOSFET to output a regulated voltage.

The Power Good signal, or PG, is an active low signal that ensures the proper output voltage. The signal is used to indicate when the output voltage is above the acceptable range and the regulator must cycle off the voltage until the output reaches the required minimum. In addition to this, the TPS60123PWPR chip supplies a thermal shutdown signal, or THERM, when the internal temperature of the device exceeds a predefined threshold. The THERM signal resets the operation of the voltage regulator in order to maintain the appliance\'s safe operating temperature.

To ensure safe operation and high reliability, the TPS60123PWPR offers integrated protection features like peak current limit, over voltage protection, short circuit protection and adjustable over-temperature protection. It also offers extended power supply up to 16 V and duty-cycle up to 95% making the regulator suitable for high power load applications. The total quiescent current of the device is only 4 mA and the conversion efficiency of 92.5% provides clean, reliable and efficient power for any application.

The TPS60123PWPR DC-DC switch regulator is equipped with many features and integrated functions to fit the power management needs of various electronic systems. Owing to its modest price, high efficiency and reliability under varying loads, the boost converter is an ideal solution for power delivery in various power-regulated systems.

In conclusion, the TPS60123PWPR DC-DC Switching Regulator is a great choice for power-managed systems, such as modern laptop and desktop computers, set-top boxes, gaming devices, TVs, embedded electronics, and other applications requiring regulated power delivery. With its operational safety features and energy-efficient operation, this cost-effective device offers reliable and clean power delivery combined with intuitive and dependable voltage regulation.
