Wanna use LMZ20501 as Dynamically Adjustable Output as
written in Application Report (SLVA251-August 2006) by Will Hadden.
In the report it used TPS63000 as an example, but my question is
is it also possible with LMZ20501?
The agent distributor of the IC in Japan said that it is not a recommended
circuit for LMZ20501. The main risk is damage of inrush current due to DAC's slew rate is too fast.
The system I plan to use as following.
1. DAC's Slew rate 1.2V/us.
DAC Full Scale =2.5V
2. Time to settled-Vout = 2ms(Max)
3. Load resistance = 30-40 Ohms
4. Voltage range = 2.68 to 3.69 V
In PSpice simulation it worked as I want, but does it really work in real?.
The main reason I want to use this IC is because its small size (Inductor on package).
