Ctrl pin connected to GND or low
level (0-1.2VDC)
Note:
(The voltage of Ctrl
pin is relative to
input pin GND.)
1. Input voltage can’t exceed this value, or will cause the permanent damage.
2. The load shouldn‘t be less than 5%, otherwise ripple will increase dramatically.
3. Max. Capacitive Load is tested on Vin-nominal and full load.
