DESIGN CONSIDERATIONS
The NE10 is a single phase and voltage mode controlled
Buck topology. The output can be trimmed in the range
of 0.59Vdc to 5.1Vdc by a resistor from Trim pin to
Ground.
The converter can be turned ON/OFF by remote control
with positive on/off (ENABLE pin) logic. The converter
DC output is disabled when
the signal is driven low
(below 0.3V). This pin is also used as the input turn on
threshold judgment. Its voltage is percent of Input
voltage during floating due to internal connection. So we
do not suggest using an active high signal (higher than
0.8V) to turn on the module because this high level
voltage will disable UVLO function. The module will turn
on when this pin is floating and the input voltage is
higher than the threshold.
The converter can protect itself by entering hiccup mode
against over current and short circuit condition. Also, the
converter will shut down when an over voltage protection
is detected.
FEATURES DESCRIPTIONS
Enable (On/Off)
The ENABLE (on/off) input allows external circuitry to
put the NE converter into a low power dissipation (sleep)
mode. Positive ENABLE is available as standard. With
the active high function, the output is guaranteed to turn
on if the ENABLE pin is driven above
0.8V. The output
will turn off if the ENABLE pin voltage is pulled below
0.3V.
Undervoltage Lockout
The ENABLE pin is also used as input UVLO function.
Leaving the enable floating, the module will turn on if the
input voltage is higher than the turn-on threshold and
turn off if the input voltage is lower than the turn-off
threshold. The d
efault turn-on voltage is 3.1V with
300mV hysteresis.
The turn-on voltage may be adjusted with a resistor
placed between the “Enable” pin and “Ground” pin. The
equation for calculating the value of this resistor is:

Safety Considerations
It is recommended that the user to provide a very
fast-acting type fuse in the input line for safety. The
output voltage set-point and the output current in the
application could define the amperage rating of the fuse.
