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 DC /DC Rx Rz 9,10,11 Vout Trim down the output voltage, R1 = 12 Adjust R1 Load Rx * Ry(Voadj - Vs) - Rz Rx * Vs - Ry(Voadj - Vs) R2 = Open Vs Trim up the output voltage, Ry R2 GND R1 = Open R2 = Rx * Ry * Vs - Rz Ry(Voadj - Vs) - Rx * Vs Nominal Output [V] Voltage Rx [K] Ry [K] Rz [K] Vs [V] 1.0 4.7 29.73 1.0 0.864 1.2 3.6 14.64 1.0 0.963 1.5 4.7 16.16 2.2 1.162 1.8 4.7 8.40 5.6 1.154 2.0 5.6 7.00 10.0 1.111 2.5 6.8 6.80 15.0 1.250 3.3 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. Please connect the input terminal by right polarity. If you connect this by mistake, it may break the DC-DC converter. In the case of destruction of the DC-DC converter inside, over input current may flow, and so DC-DC converter maybe occurred abnormal temperature rise, or your product may be damaged.
