|
Negative DC Output. This pin provides the negative regulated output from the Ag5300 and is internally connected to pin 5. |
TYPICAL SYSTEM DIAGRAM
Add 20uf / 25V capacitance at the output,This will reduce the ripple and noise to typically 140mVp-p. 24V@1A.
optional external lc filter for lower ripple and noise,This will reduce the ripple and noise to typically 40mVp-p. 24V@1A.
