STNRG011TR is a System-in-Package (SiP) power management integrated circuit (PMIC). It combines multiple DC-DC buck converters, ideal diode, and LDO regulators in a single BGA package. This enables power supply design engineers to reduce their system’s form factor by simplifying the power supply design. The SiP was designed to deliver high power density and exceptional flexibility, making it an ideal solution for power hungry applications.

Application Field

STNRG011TR can be used for a wide variety of applications including consumer electronics, communications, gaming, and industrial products. In consumer electronics, STNRG011TR is commonly used for power management in tablets, laptops, and digital cameras. In communications, it is used in the baseband and RF front-end and back-end stages of cellular base stations and smartphones. It is also used in gaming, powering game consoles and specialized gaming systems. In industrial applications, STNRG011TR is used in test and measurement, instrumentation, and embedded systems.

Working Principle

The STNRG011TR utilizes several DC-DC buck converters, an ideal diode, and a low dropout (LDO) regulator to provide the power that is needed by the system. The DC-DC buck converters are used to step down the voltage from a higher voltage source to the desired output voltage. The ideal diode is used as a protection mechanism for the system and ensures that the power supply does not become overloaded. The LDO regulator is used to provide a regulated output voltage that is continuously monitored and adjusted as needed.

The STNRG011TR supports multiple operating modes that allow the power supply to adapt to changes in the system’s demands. For example, in the step-down mode, the device provides the regulated output voltage while the input voltage remains constant. In the constant on-time mode, the device works as a switching regulator and can make frequent small-signal adjustments to the output voltage as needed. The system can also be put into sleep mode to reduce power consumption when the system is not actively in use.

The STNRG011TR’s high integration, robust design, and high efficiency make it an ideal solution for a wide variety of applications. Its flexibility in the form of multiple operating modes and the ability to make frequent adjustments to the output voltage make it the perfect choice for power hungry applications that require a reliable and efficient power supply.
