PMIC – Voltage Regulators – DC DC Switching Regulators: TS30011-M000QFNR Application Field and Working Principle

DC-DC switching regulators, also known as switching-mode power supplies, are electronic circuits used to convert a constant DC voltage from one voltage level to another. They are capable of providing high efficiency compared to linear regulators. The TS30011-M000QFNR is a DC-DC switching regulator from Texas Instruments that is typically used to regulate power from one voltage level to a much higher voltage level. This article will provide an overview of the TS30011-M000QFNR, including its application field and working principle.

Application Field of the TS30011-M000QFNR

The TS30011-M000QFNR is suitable for many applications where high efficiency and/or cost efficiency are desired, such as powering a system from a single cell battery, powering I/O interfaces, powering embedded MCUs, and powering motor drives.It is designed to regulate a constant DC output voltage from an input voltage range between 3 V and 20 V. Thus, it can be used to power systems that require an output voltage such as 5 V or 12 V, or to step down or up the voltage pass a certain level.It has a wide selection of features and protections, such as overvoltage, current limit, and thermal protection, which make it suitable for use in a wide range of applications.

Working Principle of the TS30011-M000QFNR

The TS30011-M000QFNR is a DC-DC switching regulator which uses pulse width modulation (PWM) to regulate the output voltage. It has two voltage rails, the input voltage and the output voltage. The input voltage is applied to a power switch, which is the heart of the regulator.This power switch is basically an electronic switch, which is turned on and off in a very precise manner, at a high frequency of 200kHz. When the switch is turned on, the power supply’s capacitor is charged with electricity and the voltage stored in it is stored as the input voltage. When the switch is turned off, the power supply’s capacitor discharges its voltage to the output voltage rail.By modulating the on and off time of the power switch, i.e. modulating the pulse width of the switch, the output voltage can be adjusted. The TS30011-M000QFNR also has other features such as current limit and thermal protection to provide maximum efficiency and protection.

Conclusion

In conclusion, the TS30011-M000QFNR is a DC-DC switching regulator from Texas Instruments that can be used to regulate a constant DC output voltage from a range of 3 V to 20 V inputs. It has a wide selection of features and protections that enable it to be used across a wide range of applications. It is suitable for powering systems from a single cell battery, powering I/O interfaces, powering embedded MCUs, and powering motor drives. Its working principle is based on pulse width modulation and it has current limit and thermal protection features to provide maximum efficiency and protection.
