Learn about how to overcome high frequency challenges using TI's series capacitor buck converter.
In this section, we will cover how to harden a meter against these magnetic tamper attacks by using shunts for current sensors. For poly-phase implementations, I will go over how to use isolated delta sigma modulators to add the necessary isolation to use shunt current sensors and create magnetically immune poly-phase energy measurement systems. The TIDA-00601 and TIDA-01094 reference designs, which show how to implement a poly-phase isolated shunt measurement system, will be discussed as well as the associated AMC1304 high-side power supplies used in these designs.
This training video discusses the gate driver select considerations and key specifications, and also introduces the novel gate driver specs for high end gate driver.
This training video discusses the strong gate driver introduced high dv/dt and di/dt during turn-on and turn-off switching transition, and also illustrate the high dv/dt and di/dt introduced noise through the parasitic capacitance/inductance on high side level-shift and junction capacitance on the bootstrap diode. Solutions with new state-of-the-art gate driver and its key features are introduced and explained.
Gate driver design deep dive outline:
-Parasitics in gate driver-Gate driver soft/hard switching difference-Strong gate driver and MOSFET nonlinear COSS-Common mode transient immunity(CMTI), dV/dt and di/dt through parasitics L, and C?-How to separate power ground noise by PCB layout?-Power supply for isolated gate driver in UPS, server and Telecom system-TIDA and Experimental waveforms
The first section will discuss the applications where the different kinds of gate driver will be used, and we will also identify the gate drivers location used in each typical system architecture.
This video series takes an in-depth look at voltage mode and current mode control in comparison to DCAP2 and DCAP3 control modes for step-down DC/DC converters.
DC/DC Power Modules are best known for being compact, highly-integrated power supply design options. This training series examines some of the lesser-known advantages of TI power modules:
- How do Power Modules simplify power supply design?
- Inductor withstand voltage
- High temperature storage testing
These training videos will be used to better understand LDOs, and includes more information on designing the best ADC power supply, stabilizing an LDO, measuring LDO noise and power supply rejection ratio, sourcing 5-A or more with current sharing regulators, measuring thermal resistance between junction temperature and ambiance, and measuring the ADC power supply rejection.
Engineer It is an educational, “how-to” video series where TI experts provide fundamental knowledge and solutions to overcome design challenges. Here, you can learn how to spin your motor in minutes, avoid amplifier input/output swing limitations, test and isolate power supplies and more from industry experts.
Before we dive into specific application-based examples of noise and EMI mitigation, let's start with the basics. What is EMI? How is this different from noise? What is ripple? How are they measured? What are some common approaches to limiting their effects? This section discusses these topics with a more conceptual approach to serve as a primer for the rest of the series.
Now that we understand the sources of EMI and noise in switching regulators, and some of the common approaches to mitigating each, let's take a closer look at real-world examples of reducing their effects. In this section we will examine the impacts of various mitigation techniques to help you decide which approach makes the most sense in your design. Techniques covered in this discussion include external component placement, filter options and design, frequency manipulation via spread spectrum or dithering, snubbers, boot resistors, and more.
