Up to 12 Watt | DC-DC Switching Regulator
Typical Application Circuit
Abrupt low to high inputs may damage the regulator. C1 capacitor is required to filter potentially damaging voltage spikes if high voltage is
applied. Typical value is (47µF / 100V).
NOTE: This part is not designed for parallel operation.
