The output voltage can also be programmed by
external voltage source. To make trimming less
sensitive, a series external resistor R EXT is
recommended between TRIM pin and programming
voltage source. Control Voltage can be calculated by
the formula:
The input voltage must be typically 2.05 V for the
converter to turn on. Once the converter has been
turned on, it will shut off when the input voltage
drops below typically 1.9 V.
Output Overcurrent Protection (OCP)
The converter is protected against overcurrent and
short circuit conditions. Upon sensing an overcurrent
condition, the converter will enter hiccup mode. Once
over-load or short circuit condition is removed, Vout
will return to nominal value.
Overtemperature Protection (OTP)
The converter will shut down under an
overtemperature condition to protect itself from
overheating caused by operation outside the thermal
derating curves, or operation in abnormal conditions
such as system fan failure. After the converter has
cooled to a safe operating temperature, it will
automatically restart.

Safety Requirements

International safety regulatory requirements per

R EXT ? External resistor between TRIM pin and
voltage source; the k ? value can be chosen
depending on the required output voltage range.
Control voltages with R EXT ? 0 and R EXT ? 15 k ? are

UL60950 and EN60950. The maximum DC voltage
between any two pins is Vin under all operating
conditions. Therefore, the unit has ELV (extra low
voltage) output; it meets SELV requirements under
the condition that all input voltages are ELV.
The converter is not internally fused. To comply with
safety agencies’ requirements, a recognized fuse
with a maximum rating of 20 Amps must be used in
series with the input line.

Characterization
General Information
The converter has been characterized for many
operational aspects, to include thermal derating
(maximum load current as a function of ambient
temperature and airflow) for vertical and horizontal
mountings, efficiency, startup and shutdown
parameters, output ripple and noise, transient
response to load step-change, overload, and short
circuit.
Protection Features
Input Undervoltage Lockout
Input undervoltage lockout is standard with this
converter. The converter will shut down when the
input voltage drops below a pre-determined voltage;
it will start automatically when Vin returns to a
specified range.
The figures are numbered as Fig. x.y, where x
indicates the different output voltages, and y
associates with specific plots (y = 1 for the vertical
thermal derating, …). For example, Fig. x.1 will refer
to the vertical thermal derating for all the output
voltages in general.
The following pages contain specific plots or
waveforms associated with the converter. Additional
comments for specific data are provided below.
