Output Trim Equations
Without an external resistor between Trim and GND pins, the output of the module will be 0.6Vdc. To calculate
the value of the trim resistor, Rtrim, for a desired output voltage, use the following equation:
Rtrim is the external resistor in kΩ
Vo is the desired output voltage.
Table 1 provides Rtrim values required for some common output voltages.
Table 1
By using a ±0.5% tolerance trim resistor with a TC of ±100ppm, a set point tolerance of ±1.5% can be achieved
as specified in the electrical specification.
Remote Sense
The SLIN-02E2Ax modules have a Remote Sense feature to minimize the effects of distribution losses by
regulating the voltage at the SENSE pin. The voltage between the SENSE pin and VOUT pin must not exceed
0.5V. Note that the output voltage of the module cannot exceed the specified maximum value. This includes the
voltage drop between the SENSE and Vout pins. When the Remote Sense feature is not being used, connect
the SENSE pin to the VOUT pin.
