negative On/Off logic.
Overcurrent Protection
To provide protection in a fault (output overload)
condition, the unit is equipped with internal
current-limiting circuitry and can endure current
limiting continuously. At the point of current-limit
inception, the unit enters hiccup mode. The unit
operates normally once the output current is brought
back into its specified range.
Over Temperature Protection
To provide protection in a fault condition, the unit is
equipped with a thermal shutdown circuit. The unit
will shutdown if the overtemperature threshold of
140
The thermal shutdown is not intended as a guarantee
that the unit will survive temperatures beyond its
rating. Once the unit goes into thermal shutdown it
will then wait to cool before attempting to restart.
Input Undervoltage Lockout
At input voltages below the input undervoltage
lockout limit, the module operation is disabled. The
module will begin to operate at an input voltage
above the undervoltage lockout turn-on threshold.
Output Voltage Programming
The output voltage of the 12V PicoTLynx
module can be programmed to any voltage from
0.59dc to 5.5Vdc by connecting a resistor between
the Trim and GND pins of the module. Certain
restrictions apply on the output voltage set point
depending on the input voltage. These are shown in
the Output Voltage vs. Input Voltage Set Point Area
plot in Fig. 44. The Upper Limit curve shows that for
output voltages of 0.9V and lower, the input voltage
must be lower than the maximum of 14V. The Lower
Limit curve shows that for output voltages of 3.8V
and higher, the input voltage needs to be larger than
the minimum of 4.5V.

Figure 44. Output Voltage vs. Input Voltage Set
Point Area plot showing limits where the output
voltage can be set for different input voltages.
Without an external resistor between Trim and GND
pins, the output of the module will be 0.59Vdc. 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.
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 PicoTLynx
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.
