Sense of application and precautions Notes: 1) When not using remote sense, make sure + Vo and Sense + are shorted, and that 0V and Sense- are shorted as well; 2) Keep the tracks between + Vo and Sense +, 0V and Sense- as short as possible. and close to the terminal. Avoid a looping track. If noise interferes the loop, the operation of the power module will become unstable. 1. Using remote sense with long wires may cause output voltage to become unstable. Consult us if long sensing wiring is necessary. 2. Sense tracks or wires should be as short as possible. If using wires, it should not use...
