TPS61092RSAR is a PMIC – Voltage Regulators – DC DC Switching Regulators that is integrated into a tiny 3 x 3 mm package. It is easy to use, low-cost and efficient DC-DC switching regulators that are used to convert a wide input voltage range from 1.5 V to 5.5 V to any adjustable output voltage or current between 0.9 V and 5 V. It is ideally suited for mobile applications such as smartphones and tablets, offering high power conversion efficiency and low output ripple, thus reducing noise.

The TPS61092RSAR voltage regulator has two main parts - Analog and Digital. The analog part contains the main Internal PMOS switch, an internal filter network, a synchronous rectifier, and a low-dropout linear regulator. In addition, it is possible to configure the device locally and remotely through an I2C interface.

The Operating Principle of the TPS61092RSAR follows from its design. First, The PWM controller takes the incoming voltage and decides whether to switch on or off depending on the output voltage and the voltage left across the inductor. During the switch on state, the Voltage Regulator will charge the output capacitor, drawing current from the input supply. This keeps the inductor from saturating and forces the current through the current sense resistor and the output capacitor. During theswitch off state, the Voltage Regulator gates off the switch and the current through the inductor must drop to almost zero. The inductor will now discharge its current through the output capacitor, thus generating a green output voltage.

TPS61092RSAR Application Fields include consumer electronic products such as PCs and handhelds, gaming devices, mobile phones, tablets, and the like. Developers and designers prefer this Voltage Regulator solution due to its miniature size and efficient conversions, while also offering smart control and monitoring capabilities.

TPS61092RSAR is also suitable for automotive applications as it can be used to operate Inrush Current Sensing, where it will limit the current it supplies to the system by detecting a fault as soon as it occurs, saving energy and preventing over voltage shut down. This makes it suitable for applications that need to be extremely reliable, such as electric cars, hybrid cars, and avionics systems.

The TPS61092RSAR voltage regulator operates by PWM control and is capable of converting a wide input voltage range of 1.5V to 5.5V to any adjustable output voltage or current between 0.9V and 5V. It is capable of delivering up to 650 mA of continuous output current to efficiently support applications with high loads. Developers and designers prefer its integrated device size, further reducing the number of components required for a complete solution.

Utilizing the internal filter network, the TPS61092RSAR voltage regulator also reduces noise, which is typically an issue when attempting to reach very high load densities. The filter also lowers EMI emissions, making it a versatile and reliable choice for high load density applications. Its proprietary advanced synchronous rectifier technology provides high current density and low switching losses, offering superior operational durability.

In addition to its high efficiency, the TPS61092RSAR is also equipped with an output overvoltage protection circuit that can be triggered internally or externally. This protection feature helps prevent over current or over temperature faults and ensures the device remains stable even when exposed to very high or low operating temperature.

To summarize, the TPS61092RSAR PMIC - Voltage Regulators - DC DC Switching Regulators is a highly efficient, low cost and easy to use solution for mobile and automotive applications. Its advanced synchronous rectifier technology provides superior operational durability while its internal filter and over voltage protection circuit provide greater noise and EMI reduction characteristics. With its tiny size and efficient operation, it is ideal for applications with high load densities.
