PRODUCTION DATA
The regulation loop can be compensated by adjusting the external components connected to the COMP pin. The COMP pin is the output of the internal transconductance error amplifier. The compensation capacitor will adjust the low frequency gain and the resistor value will adjust the high frequency gain. Lower output voltages require a higher gain and therefore a lower compensation capacitor value. A good start, that will work for the majority of the applications is RCOMP = 33 k? and CCOMP = 1 nF. In the case where a 22 uH inductor is used, RCOMP = 22 k? and CCOMP = 1 nF are recommended.
