* The static level of the Ctrl & Trim pin is 2KV when they are not connected to
external devices; It is suggested to connect an external capacitor (105K/50V)
from Ctrl to GND/-Vo to meet ESD ( 6KV) of the Ctrl pin, and to connect a
varistor (22V/30A) from Trim to GND/-Vo to meet ESD( 6KV) of the Trim pin.

Note:
1. All specifications measured at Ta = 25°C, humidity <75%, nominal input voltage
and rated output load unless otherwise specified.
2. In this datasheet, all the test methods of indications are based on corporate
standards.

Note:
1. The required C1 and C2 capacitors must be connected as close as possible
to the terminals of the module;
2. Refer to Table 1 for C1 and C2 capacitor values. For certain applications,
increased values and/or tantalum or low ESR electrolytic capacitors may
also be used instead;
3. Converter cannot be used for hot swap and with output in parallel.
