Notes: (1) The converter will operate down to no load with reduced specifications.
(2) The sum-total current from outputs Vo1, Vo2, and Vo3 cannot exceed 12ADC.
(3) Limits are specified by design.
(4) Measured from the application of the input voltage to the instance that all outputs are in regulation.
(5) The Enable inputs (pins 1 & 2) have internal pull-ups. Leaving pin 1 open-circuit and connecting pin 2 to –Vin allows the the converter to operate when
input power is applied. The maximum open-circuit voltage is 4V.
(6) Ultra-low ESR capacitors, such as organic or polymer aluminum electrolytic types, may cause instability. Consult the factory before using.
