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.

Note: Fault–H occurs when the output voltage level is over the OVP threshold, pass transistor in the converter is shorted when
input voltage is applied, or when a difference between input to output voltage exceeds 2.4 volts with the input voltage only at 3.3V
nominal and not at 5V nominal.
Enable L: This input signal is used to enable the output
of the converter when activated (active Low). The
signal is referenced to output side (-Sense) or GND.
