Feature Description
Remote On/Off
Two remote on/off options are available. Positive logic
turns the module on during a logic high voltage on the
ON/OFF pin, and off during a logic low. Negative logic
remote On/Off, device code suffix “1”, turns the module
off during a logic high and on during a logic low.
To maintain compatibility with LW series power modules
the Remote On/Off pin is optional for the TH (through
hole) version. Standard TH modules have no On/Off pin
fitted. TH modules ordered with device code suffix “1”
are negative logic with the On/Off pin fitted. The On/Off
pin shall always be fitted on SMT versions.

Figure 46. Circuit configuration for using Remote
On/Off Implementation.
To turn the power module on and off, the user must
supply a switch (open collector or equivalent) to control
the voltage (Von/off) between the ON/OFF terminal and
the VIN(-) terminal. Logic low is 0V ≤ Von/off ≤ 1.2V. The
maximum Ion/off during a logic low is 1mA, the switch
should be maintain a logic low level whilst sinking this
current.
During a logic high, the typical Von/off generated by the
module is 5.8V, and the maximum allowable leakage
current at Von/off = 5.8V is 50μA.
If not using the remote on/off feature:
For positive logic, leave the ON/OFF pin open.
For negative logic, short the ON/OFF pin to VIN(-).
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. The average output current during hiccup is 10%
IO, max.
Input Undervoltage Lockout
At input voltages below the input undervoltage lockout
limit, the module operation is disabled. The module will
only begin to operate once the input voltage is raised
above the undervoltage lockout turn-on threshold,
VUV/ON.
Once operating, the module will continue to operate until
the input voltage is taken below the undervoltage turn-off
threshold, VUV/OFF.
Over Voltage Protection
The output overvoltage protection consists of circuitry
that internally clamps the output voltage. If a more
accurate output overvoltage protection scheme is
required then this should be implemented externally via
use of the remote on/off pin.
Output Voltage Programming
Trimming allows the user to increase or decrease the
output voltage set point of the module. This is
accomplished by connecting an external resistor
between the TRIM pin and either the Vout+ pin or the
Vout- pin.
Note: Trim pin is optional on TH module version and
always present on SMT versions.
Trim Down – Decrease Output Voltage
By connecting an external resistor between the TRIM pin
and Vout+ pin (Radj-down), the output voltage set point
decreases (see figure 17). The following equation
determines the external resistor value to obtain an
output voltage change from Vo, nom to the desired Vo,
