Part Number: LM2577 Hello, Im trying to desing a DC-DC converter as a forward, based on the application note: AN-776 20 Watt Simple Switcher Forward Converter (Rev. A). First of all the subscripts of the variables changes every time and it makes difficult…
Part Number: LM2577 Hi,
I have a circuit where I use LM2577 to boost Vin to Vout (24V).
In most cases Vin < Vout and all is according to spec.
However there might be situations where Vin >= Vout.
So will Vout = Vin - V_diode (from the schottky diode…
Part Number: LM2577 Stuck on the LM2577 again
I have the design bread-boarded and sort of working for 12Vin and +-15 volts out so that means I willl require the Snubber circuit as well.
as the the transformer is Lp=200 and the input voltage is 12 and…
Part Number: LM2577 Other Parts Discussed in Thread: LM5118 , LM5156 , LM5155 Hi, we have a varying voltage source (from a generator) that can have a wide voltage range from 6-30V. This voltage has to be regulated to a stable 24V output for an external…
Part Number: LM2577
Is this a typo on the DataSheet
or is that referring to the >=47 uf cap from this paragraph
and the designer picked 100uf vs 47uf
And one more quick question.
Am I correct in assuming this 100uf cap would be an electrolytic…
Part Number: LM2577 Hi,
We are noticing a discoloration of the exposed metal only on this particular part after Reflow soldering.
This is evident in the picture below when comparing the lead color to that of other components.
There is no issue with the…
Part Number: LM2577 I'm using the LM2577SX-ADJ/NOPB and I would like to confirm the over TI_LM2577.docx current limit at 9.3V and 11.54V. TI_LM2577.docx
Part Number: LM2577 I am attempting to boost a 120AC mains rectified to 170V up to 220V for a design project. I've been trying to find a controller for a boost converter and this one seems to be the best option. Would you recommend using this for high…
