Output Voltage Programming
The output voltage of the NE series is trimmable by
connecting an external resistor between the trim pin and
output ground as shown Figure 21 and the typical trim
resistor values are shown in Table 1.

FEATURES DESCRIPTIONS (CON.)
The ENABLE input can be driven in a variety of ways as
shown in Figures 19 and 20. If the ENABLE signal
comes from the primary side of the circuit, the ENABLE
can be driven through either a bipolar signal transistor
(Figure 18).If the enable signal comes from the
secondary side, then an opto-coupler or other isolation
devices must be used to bring the signal across the
voltage isolation (please see Figure 19).

Input Under-Voltage Lockout
The input under-voltage lockout prevents the converter
from being damaged while operating when the input
voltage is too low. The lockout occurs between 2.8V to
3.1V.
Over-Current and Short-Circuit Protection
The NE series modules have non-latching over-current
and short-circuit protection circuitry. When over current
condition occurs, the module goes into the non-latching
hiccup mode. When the over-current condition is
removed, the module will resume normal operation.
An over current condition is detected by measuring the
voltage drop across the MOSFETs. The voltage drop
across the MOSFET is also a function of the MOSFET’s
Rds(on). Rds(on) is affected by temperature, therefore
ambient temperature will affect the current limit inception
point. Please see the electrical characteristics for details
of the OCP function.
The detection of the Rds(on) of MOSFETs also acts as
an over temperature protection since high temperature
will cause the Rds(on) of the MOSFETs to increase,
eventually triggering over-current protection.
