Notes: 1. Connector J1 pins 1, 2, 3, and 5 are all connected together. Connector J1 pin 4 is always connected to 3.3V rail.
2. 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.
3. The converter output voltage shall be stable when (30) 330µf (9900µF total) tantalum (ESR ≤60mΩ) capacitors are
connected across the output of the converter.
4. Adjustment pins J2-18 & 19 are normally left open; see Table IV if using OVP and output voltage trim adjustment.
