Note: 1.“*” are models under developing. 2.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 load.

Single( S)Dual(D) * Note: if the definition of pin is not in accordance with the model selection manual, please refer to the label on actual item. Packing Code 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...

4.CTRL Terminal Suspended or high resistance, output of module runs normally; Connect to high level(relative to input ground), module turns off. Note: The proper current flowing into this pin is 5-10mA. It will cause permanent damage to module if the current exceed its maximum value(typically 20mA). The R is calculated according to the following formula: Vc is the input voltage of Ctrl, Vd is forward voltage drop of D1，0.7V and 330Ω are module’s bipolar junction transistor voltage drop and inside connecting resistor of input terminal for control pin respectively, Ic is the input current of control...
