I need to know the saturation current & power handling capacity of my Inductor/Toroidal core which I want to use in a SMPS to power up several LEDs.
Infos:
Toroidal core= Iron Powder (size- T44(OD=11.2, ID=5.82, h=4.04 all mm), color/material-26 (yellow/white), AL=37nH/N2)
Inductance=137.67uH (61turns of 0.457mm wire)
SMPS: Boost converter. Input 3.7v (may vary)
Duty cycle & frequency are variable, but for easy calculation consider 50% duty & 50kHz freq.
I want to know
-the capacity (max current, power) of the core
-how to calculate these.
I’ve a bunch of toroidal cores (scavenged). I want to design circuit & use the most suitable one of those.
Anybody Please help.
