PRODUCTION DATA
FB is the inverting input of the error amplifier. The noninverting input to the error amplifier is internally trimmed to 2.5 V ± 1%. FB is used to control the power converter voltage-feedback loop for stability. For best stability, keep FB lead length as short as possible and FB stray capacitance as small as possible.
