1. The max. capacitive load was tested at input voltage range and full load.
2. Unless otherwise specified, parameters were measured under the conditions
of Ta=25°C, humidity<75%RH with nominal input voltage, 5VDC output voltage
and rated output load.
Unless otherwise specified, parameters in this table were measured under the
5VDC output voltage.
3. All index testing methods in this datasheet are based on our Company’s

X: Suffix “P” indicates that the Ctrl pin is positive logic control, “N” indicates that the Ctrl pin is negative logic control.
Unless otherwise specified, parameters in this table were measured under the 5VDC output voltage.
1. Exceeding the maximum input voltage may cause permanent damage.
2. The default output voltage is 0.75VDC, which can be adjusted to 1.2VDC, 1.8VDC, 2.5VDC, 3.3VDC, 5VDC. See Trim instructions for specific output
voltage adjustment.
Typical characteristics
Typical application
LOT10-10R-X
Note:
1. 100 µF or 220 µF capacitor (C1) and 22 µF or 47 µF capacitor (C2) are required
and should be connected close to the pin terminal, to ensure the stability of the
converter;
2. To reduce the output ripple furtherly,increased values and/or tantalum or low
ESR electrolytic capacitors may also be used instead;
3. Refer to Table 1 for C1 and C2 capacitor values;
4. Converter cannot be used for hot swap and with output in parallel.

Trim function
Trim function for output voltage adjustment (open if unused)
Notes: 1. RT : Resistance of Trim; Vo: The trim up voltage;
2. If RT = ∞ or Trim pin open, Vo = 0.7525 VDC.
Remote sense application
Remote sense connection if not used
Note:
1. If the sense function is not used for remote regulation the user
must connect the Sense to + Vo at the DC-DC converter pins
and will compensate for voltage drop across pins only;
2. The connections between Sense and +Vo must be kept as short
as possible, otherwise they may be picking up noise, interfe-
rence and/or causing unstable operation of the power module.
Remote sense connection used for compensation
Note:
1. PCB-tracks or cables/wires for Remote Sense must be kept as
short as possible;
2. Using remote sense with long wires long wires may cause
unstable operation. Note that large wire impedance may
cause oscillation of the output voltage and/or increased ripple.
Consult technical support or factory for further advice of sense
operation;
3. We recommend using adequate cross section for PCB-track
layout and/or cables to connect the power supply module to
the load in order to keep the voltage drop below 0.3V and to
make sure the power supply‘s output voltage remains within
the specified range.
