Output Voltage adjustment l When Adjust-pin (12pin) is left open, DC-DC converter applies nominal output voltage. l Resistors connected between Adjust-pin(12pin) to Vout-pin (9~11pin) will decrease the output voltage between 90% ~ 100% of the nominal output voltage.(Vout-Down control) l Resistors connected between Adjust-pin(12pin) to GND-pin (5~8pin) will increase the output voltage between 100% ~ 110% of the nominal output voltage.(Vout-Up control) l The following equations give the required external-resistor value to adjust the output voltage to Voadj. When you change the output voltage, it is necessary to evaluate the characteristics of DC-DC converter at your board conditions. l When Vout-Up is used, the input voltage must higher than the output voltage the following rate: l AVC (Vin=3.3V) Vin > Vout+0.5V AVC (Vin=5V) Vin > Vout+1.0V 9,10,11 Vout DC /DC Trim down the output voltage, Rx * Ry(Voadj - Vs) - Rz Rx * Vs - Ry(Voadj - Vs) R2 = Open R1 = Rx Rz 12 R1 Adjust Load Trim up the output voltage, Vs Ry R1 = Open R2 R2 = GND Rx * Ry * Vs - Rz Ry(Voadj - Vs) - Rx * Vs <Internal parameter of DC-DC converter> Nominal Output [V] Voltage Rx [KΩ] Ry [KΩ] Rz [KΩ] Vs [V] 1.0 1.2 1.5 1.8 2.0 2.5 3.3 4.7 29.73 1.0 0.864 3.6 14.64 1.0 0.963 4.7 16.16 2.2 1.162 4.7 8.40 5.6 1.154 5.6 7.00 10.0 1.111 6.8 6.80 15.0 1.250 8.2 4.60 18.0 1.186 MODEL : AVC 20W SERIES April 05 REVISION 02 SHEET 7 OF 16 Technical Reference Note Ultra Low Profile AVC 20W Series Be sure to provide an appropriate fail-safe function on your product to prevent a second damage that may be caused by the abnormal function or the failure of our product.
