Notes: 1. Input filter capacitor Cin= 1000µF (330µF, ESR 60mΩ, 3 capacitors in parallel) Provide 3" loop between positive
terminal of Cin and Vin of the converter to measure reflected input ripple current.
2. The converter output voltage shall be stable when (30) 330µF (9900µF total) tantalum (ESR ≤60mΩ) capacitors are
connected across the output of the converter.
3. Adjustment pins J2-18 & 19 are normally left open; see Output Voltage Setting Table on page 5 if using OVP and
output voltage trim adjustment.
