LOT10_10R-X Series
10A - Non-Isolated & Regulated, Single output POL power converter
Switching Regulator
Efficiency up to 94%
Input under-voltage, over-
current protection
High-speed transient response
EN62368 approved
The LOT10_10R-X is a 10A non-isolated switching regulator. The output
voltage is accurately adjustable from 0.75V to 5.0V, and the product is
featured with high efficiency, fast transient response, input under-volta-
ge, output short circuit and over-current protection. It meets CLASS B of
CISPR32/EN55032 EMI standards by adding the recommended external
components.
Operating temperature range:
-40°C ~ +85°C
Short circuit protection (SCP)
Compact SMD package
They are widely used in applications such as communications, computer
network industry, power distributed architecture, workstations, servers,
LANs/WANs and provide high current with fast transient response for
high-speed chips such as FPGA, DSP, and ASIC.

Note:
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
corporate standards.
