... STLC3055N The STLC3055N feeds the line with a constant current fixed by RLIM ( range). The on-hook voltage is typically 40 V allowing on-hook transmission; the self generated Vbat is -50 V typ. If the loop resistance is very high and the line current cannot reach the programmed constant current feed value, the STLC3055N behaves like voltage source with a series impedance equal to the protection resistors 2xRp (typ Ω ...

... As a first recommendation the components CV, L, D1, CVPOS, RSENSE should be kept as close as possible to each other and isolated from the other components. Additional improvements can be obtained: ● decoupling the center of the star from the analog ground of STLC3055N using small chokes. ● adding a capacitor in the range of 100 nF between VPOS and AGND in order to filter the switch frequency on VPOS ...
