Data Sheet
March 31, 2011
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.
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 12V Pico TLynx
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.
