Manufacturer:ATMEL Description:The AT47BV163A-70TU keeps a constant 1.2V between the VFB pin and ground pin. By placing a resistor R1 across these two pins a constant current flows through R1, adding to the AT47BV163A-70TUFB current and into the R2 resistor producing a volt- age equal to the (1.2/R1)3R2 + AT47BV163A-70TUFB3R2 which will be added to the 1.2V to set the output voltage as shown in the above equation. Since the input bias current of the amplifier (AT47BV163A-70TUFB) is only 0.02mA typically, it adds a very small error to the output voltage and for most applica- tions can be ignored. For example, in a typical 1.5V GTL+application if R1=10.2KV and R2=2.55KV the er- ror due to the AT47BV163A-70TU DJ is only 0.05mV which is less thanA 0.004% of the nominal set point. The effective input im- pedance seen by the feedback pins (The parallel combi- nation of R1 and R2) must always be higher than 1.8KV in order for the regulator to start up properly. |
