Note that this is already greater than the mA that the chip is specified to handle. With a minimum input voltage of 3. They have a similar example datasgeet the ds for 15V mA,where the inductor is uH.
DC motor speed control using LM3578
As I mentioned the ebay item which I procured has similar behavior during startup.
The inductor in this configuration does not limit the output current. Your 1 nF capacitor sets the oscillator frequency adtasheet about 80 kHz, which is a You’re overloading it, and this is going to cut into your overall efficiency, dropping as much as 0. Email Required, but never shown.
DC motor speed control using LM
But if the inductor is saturating, it’ll never get there.

The problem I am facing is that the voltage takes about 10s. Home Questions Tags Users Unanswered. The excessive sag in battery voltage suggests that the circuit is lm5378 far more current than it should during startup, while the slow rise in output voltage suggests that the current is too low for some reason.
There is a current limiting resistor,so that should prevent excessive draw,even during start up?

In both circuits sometimes, rarely it powers up immediately,which is quite perplexing. EmbSysDev 1 1 Will it work correctly without pin 2 connected? Post as a guest Name. During this time the battery voltage falls to about 1. The datasheet only guarantees operation from 2V, so if llm3578 batteries are sagging below that, you’ll either need some sort of soft-start circuit or some extra cells to stay above the minimum operating voltage.
I would focus on the coil. I procured a similar circuit from here.
