PRODUCTION DATA
RFB1 and RFB2 set the output voltage level, the ratio of these resistors is calculated from:
RFB1 is typically 1.21 k? for a divider current of 1 mA. The divider current can be reduced to 100 μA with RFB1=12.1 k?. For the 5V output design example used here, RFB1 = 1.21 k? and RFB2 = 3.74 k?.
