The values for trim resistors shown in trim tables below are according to standard E96 values; therefore, the specified voltage may slightly vary; they also can be calculated with below shown equation. R1 TRIM -Sense TRIM R2 +Sense TRIM DOWN TRIM UP Trim Calculation Vout = nom. Output Voltage DVout = Output Voltage Change in % Rup = trim up resistor Rdown = trim down resistor Rup = 45 + 40 k Ω DVout Rup = 45 + 40 k Ω = 490kΩ (E96 = 490) 10% Rdown = 5.11 - 10.22 k Ω = 53.66kΩ (E96 = 53.6) 8% Rup = 57.46 + 52.35 k Ω DVout Rup = 95 + 90 k Ω DVout Rdown = 5.11 - 10.22 k Ω DVout Rup = 195 + 190 k Ω DVout Trim down: Vout = 24V, DVout = -8% (22V) Trim Up: Vout = 12V, DVout = +10% (13.2V) Practical Example 12Vout Trim up Trim down 15Vout 24Vout 48Vout |
