YNL05S100xy DC-DC Converter Family Data Sheet
3.0 to 5.5 VDC Input; 0.9 to 3.3 VDC @ 10 A Output
Protection Features
To trim down the output voltage (Fig. F), a trim
resistor, R T-DECR , should be connected between
the TRIM pin (Pin 3) and SENSE pin (Pin 2), with a
value of:
For V O-NOM ≥ 1.2 V,
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 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

Output Overcurrent Protection (OCP)
The converter is protected against overcurrent and
short circuit conditions. Upon sensing an overcurrent

an over-load or short circuit condition is removed,
Vout will return to nominal value.

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

Standard 1% and 5% resistors can be used for
trimming. Ground pin of the trim resistor should be
connected directly to the module GND pin (Pin 5)
with no voltage drop in between.
The output voltage can be trimmed up or down using
an external voltage source:
For V O-NOM ≥ 1.2 V,
automatically restart.
Safety Requirements
The converter meets North American and
International safety regulatory requirements per
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

General Information
The converter has been characterized for many
operational aspects, to include thermal derating
