TL494: TL494 equivalent for flyback topology with native current sensing

John Jones

Part Number: TL494

Does such an IC exist? Where the parameters for the rest of the IC are similar except it natively supports flyback topology and has some kind of current sensing for a resistor in the primary switch current path?

Thanks.

Hi John,

TL494 can be used for flyback topology. A application note for your reference.

Oh thanks I hadn't seen that before.

But there's definitely no similar IC available with the current sensing built in?

Hi John,

Sorry I didn't find a similar device.
