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...

device number Calculation formula of Trim resistance: Vo'-Vref Vref Rt is Trim resistance ,a is a self-defined parameter, with no real meaning. Vo' for the actual needs of the up or down regulated voltage Trim up Trim down Applied circuits of Trim (Part in broken line is the interior of models) When the Trim function with down regulated is used, If the RT resistor is too low or “Trim" is short with “+Vo", the output voltage Vo' would be lower than 0.9Vo, which may cause the product to be irreversibly damaged.
