Output Trim Equations
Equation for calculating the trim resistor given the desired output voltage (Vo) is shown below. The Rtrim resistor
should be connected between the trim pin and GND pin.
Over Current Protection
The module is equipped with internal current-limiting circuitry in order to provide protection in a fault output
overload condition. The module will be in hiccup mode when the output current exceeds the current limit.
