TPS61120PWRG4 is a highly integrated power supply unit designed for multiple applications with limited space, providing efficient and reliable power performance. As a specialized power management integrated circuit (PMIC), the device can be used for a wide range of applications such as lighting and display, portable devices, and automotive. This article will discuss the application field and working principle of the TPS61120PWRG4.

The main components of the TPS61120PWRG4 are three high current integrated switches for a 1-channel synchronous buck converter, and a control circuit, including a 2.5V reference, error amplifier, current/voltage loop compensator, slope compensation and clock sync. The extremely low quiescent current consumes only 6uA when the device is disabled.

The TPS61120PWRG4 is designed to work effectively in small systems with limited space, such as wearable devices and cellular phones. Its wide input voltage range of 0.9V to 1.6V and high efficiency makes it suitable for applications such as powered cameras and displays. Moreover, the device has an adjustable switching frequency up to 1MHz, providing more flexibility in various applications.

The TPS61120PWRG4 provides several protections, such as output overvoltage, overtemperature, and overcurrent. Moreover, it enables several features such as current-mode control and soft-start. These features provide stability and protection in wide range of operating conditions and ensure that the device is operating within the given parameters.

The TPS61120PWRG4 provides a single 1-channel synchronous buck converter for high efficiency. In 1-channel buck converter, the input voltage is stepped down by passing a current through a MOSFET switch. The amplifier and freewheeling diode allow the current to be shared and regulate the output voltage. The output voltage is then transmitted to the load.

The working principle of the device is based on current-mode control. The current-mode control enables high-speed transient response, adjustable current loop bandwidth, output current sensing accuracy and temperature stability. The reference voltage is used to set the maximum current limit, while the error amplifier keeps the output current at the desired level. The slope compensator and oscillator add extra control to the current-mode control to enhance performance. Additionally, the overcurrent protection blocks further load current if the load current exceeds the maximum level.

The TPS61120PWRG4 is a specialized PMIC device with a wide range of features. The wide input voltage range, adjustable switching frequency, high efficiency, and current-mode control makes the device suitable for a large number of applications. Moreover, the integrated protection features and the low quiescent current ensure that the device operates efficiently and reliably in different operating conditions.
