Sign up or log in Sign up using Google. In both circuits sometimes, rarely it powers up immediately,which is quite perplexing.
They have a similar example in the ds for 15V mA,where the inductor is uH. Note that this is already greater than the mA that the chip is specified to handle.
You’re overloading it, and this is going to cut into your overall efficiency, dropping as much as 0. After this the circuit works pretty fine.
As I mentioned the ebay item which I procured has similar behavior during startup. Post as a guest Name. Hello all, I have this circuit which will take an input 4×1. Laszlo 1 I am doing this on a proper pcb with a ground plane,initially i had used a DIP version on a stripboard,with slightly better results.
Datashet this l,3578 the battery voltage falls to about 1. EmbSysDev 1 1 There is a current limiting resistor,so that should prevent excessive draw,even during start up?
DC motor speed control using LM
The inductor in this configuration does not limit the output current. Email Required, but never shown.
I would focus on the coil. Your 1 nF capacitor sets the oscillator frequency at about 80 kHz, which is a Slow start up of LM Ask Question. Any suggestions on how to improve this?
Your symptoms are actually a bit contradictory. Sign up using Facebook. The problem I am facing is that the voltage takes about 10s. Sign up using Email and Password. I procured a similar circuit from here.
