Tool/software:
Hi There,
Im modelling the UC2856 for spice simulation, Im working on Error amplifier section in which I required some missing parameters in the datasheet as below:
1.Input Impedance
2.Output impedance
3.Ao (Voltage gain) value at RL(Outpur Load)= Infinity
Please provide the detailed values as per above required parameters
Thanks,
Nikhil
Hi,
These are ok to get from the below datasheet.
1. VFB max 40V, current 1uA, so 40M ohm
2. COMP = 2.5V, its current = 0.5mA, so output impedance = 2.5V/0.5mA = 5k-ohm for source current, for sink, 1.2V/10mA = 120 ohm
3. 100 dB
