... With the active high function, the output is guaranteed to turn on if the ENABLE pin is driven above 1.5V. The output will turn off if the ENABLE pin voltage is pulled below 0.8V. The D12S400 is turned on if the ENABLE pin is floating. The ENABLE input can be driven in a variety of way as shown in Figures 25 ...

... Hence, paralleling of multiple converters are not recommended. Output Capacitance Rtrim There is output capacitor on the D12S400. Hence, no external output capacitor is required for stable operation. Reflected Ripple Current and Output Ripple and Noise Measurement The measurement set-up outlined in Figure 27 has been used ...
