how calculate the current regulator parts? and i can"t set the null with trimpot and resistor between pin 1 and pin 5 of the opamp. Opamp - TLE2141, trimpot - 4.7k and resistor 1k, output voltage is change from 22mV to 33mV.. maybe i need to increase or decrease the value of resistor (1k)? Sorry for my english, iam fron russia :) Thanks

Hi all can i change the value of 10W resistor to 0.1 Ohm? (project 30V 3A output)

Picmaster, can you upload the pcb and BoM?
