Part Number:LM25119
hello,
i m planning to design a converter with parameters below:
Vin: 28V
Vout: 25V
Iout: 25A (can be set by external sources to 20A or 15A or 10A)
with this controller and its application circuit.
how can i add output current setting option without changing any hardware?
is it possible to set output current with adding some voltage to ramp pin? as i read from datasheet, output current set is depended on 2 things, 1. Cs pin (Sample and
Hold DC Level) and ramp slope.
for me it is not possible to add some slope externally but i can add some DC level to this pin. is it useless? or any other idea?
the point is, users could be able to set output current to those values mentioned above via software (software will change this level on ramp pin?)
Apart from that, can I use any other component for this kind of application.
