TPS62233DRYR - Applications and Working Principle

PMIC (Power Management IC) are integrated circuits that are used to control and manage the supply of power to a device. They allow devices to consume less power while still providing a high level of performance. One type of PMIC is the DC to DC voltage regulator, which is used to regulate the voltage of an input power supply. The TPS62233DRYR is a monolithic, single-channel, synchronous, step-down DC to DC switching regulator designed to provide a regulated output voltage with minimum external components.

Applications

The TPS62233DRYR has a wide range of applications, such as powering LED drivers, mobile baseband power supplies, point-of-load regulators, USB Type-C and PD (Power Delivery) power sources, and many more. Its low quiescent current and minimum power dissipation make it ideal for low-power and portable applications, like wearable electronics and Internet-of-Things (IoT) devices. It also features an adjustable output, making it suitable for use in a variety of systems.

Features

The TPS62233DRYR features an integrated 54 mΩ/45 mΩ high- and low-side MOSFETs, respectively, which help to minimize external components. It can accept a wide input voltage range of 4.5 to 30V, making it very versatile in terms of input source. It also has a maximum output current of 1.5A and a wide output voltage range of 0.6 to 5.5V, making it suitable for a variety of applications. In addition, other features include: a low quiescent current of 6.2 µA, High efficiency up to 94%, fast transient response, and thermal protection.

Working Principle

The TPS62233DRYR is a step-down, synchronous switching regulator that uses pulse-width modulation (PWM) to regulate its output voltage. When keyed on, the high-side and low-side MOSFETs switch alternatively to create a square wave with a fixed frequency. The output voltage is regulated through adjusting the duty cycle of the square wave, which produces a PWM signal to control the output voltage. The regulators\' voltage regulation loop senses the output voltage and adjusts the PWM duty cycle accordingly. This results in the output voltage remaining constant even if the input voltage changes.

Conclusion

The TPS62233DRYR is a DC to DC switching regulator used to regulate the voltage of an input power source. It has a wide range of applications, including LED drivers, mobile baseband power supplies, and point-of-load regulators, and is suitable for a variety of systems due to its adjustable output voltage. It features an integrated high- and low-side MOSFETs and has a wide input and output voltage range, allowing it to be used in many types of devices. Its low quiescent current and high efficiency make it ideal for low-power and portable applications. Its working principle involves using pulse width modulation to control the output voltage.
