1.CS terminal This terminal provides a connection point to connect the inside main filter capacitor of output terminal for the DC/DC converter(capacitor positive) , and can further improve the output ripple and noise (Normal CS≤47uF) through connecting a low ESR capacitor between this terminal and the 7 pin (capacitor negative). 2.Output Load Request a. To ensure this module operate efficiently and reliably, the minimum load could not be less than 10% of the nominal load. If the actual power is too small, please connect a resistor in parallel at output terminal, the resistance equal to 10% nominal...

5.Input Current When unstable power supply connected, please ensure that the output voltage fluctuating range of power supply and the ripple voltage is within the module’s index, output current of input power supply must be able to meet instant turn-on current Ip of the DC/DC converter(see below picture) Normally: Ip 6.Ripple& Noise Test: (Twisted Pair Method 20MHZ bandwidth) Test Method: a.12# twisted pair to connect, Oscilloscope bandwidth set as 20MHz, 100M bandwidth probe, terminated with 0.1uF polypropylene capacitor and 47uF high frequency low resistance electrolytic capacitor in parallel,...
