TPS57140QDGQRQ1 is a type of switching regulator that is designed for applications that need to produce several output voltages and do so with excellent accuracy. The regulator has internal current feedback, allowing for very accurate voltage regulation. The design of the regulator includes a low side switch, a high side switch, and an integrated gate driver circuit. This regulator can be used in both single and multiple output configurations, and is suitable for applications such as telecom, consumer electronics, computing, portable devices, automotive, and industrial control.
Features and Benefits
The TPS57140QDGQRQ1 offers many features that make it an ideal choice for businesses seeking to incorporate a reliable, cost-effective DC/DC conversion solution. The regulator is equipped with an integrated gate driver, making it easy to take the regulator from testing to product realization quickly. Additionally, a thermal shutdown feature prevents the device from overheating, safeguarding against its destruction when exposed to a fault condition.Application Field
The TPS57140QDGQRQ1 is suitable for a variety of applications, including telecom, consumer electronics, computing, portable devices, automotive, and industrial control. This regulator can be used in both single and multiple output configurations and provide excellent regulation accuracy.The TPS57140QDGQRQ1 is designed to enable efficient-conversion from input voltages of +3.3V to +1.8V, +3V, and +3.3V and up to 8A of output current. This makes them suitable for applications such as DDR memory supplies, clock distribution, and general DC/DC switching power supplies.Working Principle
The TPS57140QDGQRQ1 works in the same way as other switching power regulators – by using pulse-width modulation (PWM) to regulate its output voltage. The internal current feedback loop is used to compare the output voltage to a reference voltage and adjust the duty cycle of the output PWM signal accordingly. This allows the regulator to provide high precision voltage regulation even under dynamic loads and high input voltages.The regulator includes an integrated low-side switch, a high-side switch, and a dedicated gate driver circuit. This helps keep the design simple, enabling designers to incorporate the regulator into their designs quickly and easily.The TPS57140QDGQRQ1 also includes an accurate Current Mode Controller with an external compensated voltage reference and a temperature-compensated IC-based current limit. This helps ensure that the regulator provides reliable power delivery while operating safely and efficiently.Conclusion
The TPS57140QDGQRQ1 is a type of switching regulator that is designed for applications that need to produce several output voltages with excellent accuracy. This regulator is suitable for applications such as telecom, consumer electronics, computing, portable devices, automotive, and industrial control. The TPS57140QDGQRQ1 also features an integrated gate driver, an accurate current-mode controller, and a temperature-compensated IC-based current limit, making it a reliable choice for businesses seeking a cost-effective DC/DC conversion solution.The specific data is subject to PDF, and the above content is for reference
