Hello Power Gurus,
I look at a lot of datasheets across manufactures, and I am wondering what suggestions other engineers may like to see added or refined when they are designing in a buck, boost, etc. Several ideas come to mind:
What are your gripes of industry datasheets?
I look at a lot of datasheets across manufactures, and I am wondering what suggestions other engineers may like to see added or refined when they are designing in a buck, boost, etc. Several ideas come to mind:
- Additional datasheet graphs over voltage, load, temperature.
- provide the temperature, what trim if any, specific inductor, specific capacitor, etc.
- Bode plots for the converter?
- Details on the suggested inductor/capacitor with an actual part number (not all XR7 dielectrics are the exact same performance)
- Layout considerations or examples
- Detailed design walkthrough (could be related to #2)
- A little difficult due to undocumented slope compensation and other IC trims. "Use this value" is usually the datasheet advice
- Detailed description of expected performance (behavior is startup, short circuit, over temperature, etc.)
- ABS MAX ratings details
- A tough one is the LX node to ground. Often stated to be VDD - 300mV, but in reality this can be -1V or more in normal operation. Worst case is at full current limit at 125C.
- And maybe not critical, but graph colors. TI has ugly colors, but I suspect these are for printing and color blindness.
