Minimize the impact of the MLCC shortage using D-CAP+™ control mode
As my colleague Yann said in an earlier blog , there is a growing shortage of multilayer ceramic capacitors (MLCCs), and the situation is likely to persist through 2020. MLCCs are used in almost every type of electronic equipment, due to their reliability and small footprint. Manufacturers are now looking to replace ceramic capacitors with polymer...

4 Reasons why you should use a boost charger for 2-cell battery application
(Note: Eric Zhao co-authored this blog post.) Finding the perfect battery charger integrated circuit (IC) for your portable electronic device design is not always easy, especially when you need a battery with more than one cell in series (1S) for hig...

No avalanche? No problem! GaN FETs are surge robust
We live in silicon-dominated world that shapes our thinking. I find it interesting to imagine an alternate universe where the gallium nitride (GaN) power field-effect transistor (FET) was developed before the silicon FET. Our power converters would c...

Minimize the impact of the MLCC shortage on your power application
There is a growing shortage of multilayer ceramic capacitors (MLCCs), and the situation is likely to persist through 2020. MLCCs are used in almost every type of electronic equipment, due to their reliability and small footprint. While MLCC manufacturers are taking action to increase their production capacity, demand is still expected to outpace...

How to make a simple nonmagnetic AC/DC power supply
When creating an industrial power supply, one of the most common challenges is transforming the AC voltage supply into a DC voltage supply. Changing an AC voltage to a DC voltage is necessary for nearly every application, from charging cellphones to powering a microcontroller for a microwave. Typically, this conversion occurs through the use of a transformer...

20 million GaN reliability hours and counting
"My advice is to get involved and get started,” — Jack Kilby About 20 million reliability hours ago, we built our first gallium nitride (GaN) application board in TI’s Kilby Labs. We watched the oscilloscope in anticipation an...
