TPS62650TYFFRQ1 Integrated Circuits (ICs)

TPS62650TYFFRQ1 is a voltage regulator from Texas Instruments, classified as a DC-DC switching regulator, specifically a synchronous step-down (buck) voltage regulator. This regulator is ideal for surge current and low-noise applications that typically employ multiple linear regulators and inductors. This regulator offers precision output voltage and current capability, along with excellent thermal performance. It is capable of operating over a wide input voltage range with a fixed operating frequency and provides precise rise time control.

The TPS62650TYFFRQ1 regulator consists of a power MOSFET switch, a voltage reference, current and voltage sensing, as well as optimization circuitry. When the power MOSFET is turned on, current charges up the inductor followed by the capacitor that is connected to the output. When the power MOSFET is turned off, inductor current discharges into the output. This cycle is continually repeated at a frequency determined by the internal oscillator, controlling the time during which power MOSFET is on and off. The maximum output current even under heavy load conditions, and the maximum temperature rise, is determined by the current sense, temperature sense and thermal protection circuitry.

The TPS62650TYFFRQ1 is well suited for a variety of fast transient applications including smartphones and tablets, personal electronics devices, and a wide range of other portable equipment. With its wide input voltage range, the device is capable of powering over a variety of battery chemistries, such as Li-Ion, while providing a wide range of output current levels. In addition, the regulator includes advanced design protection features, such as short-circuit protection, over-voltage protection, and thermal protection, making it a suitable choice for high power applications.

The regulator can also provide additional features such as power-saving modes for low-power scenarios, and voltage regulation for higher currents with lower noise. It is designed for reliable operation even under harsh environmental conditions and offers improved performance for demanding applications. With its high efficiency and fast transient response, the TPS62650TYFFRQ1 regulator provides superior performance and reliability.
