PRODUCTION DATA
For best stability, external compensation components should be placed close to the IC. Keep VFB lead length as short as possible and VFB stray capacitance as small as possible. Surface mount components are recommended here as well for the same reasons discussed for the filter capacitors. These should not be located very close to traces with high switching noise.
