Small footprint
Temperature range:
The 2S7A_1U series is a family of cost effective 2W single & dual output
DC-DC converters. These converters achieve low cost and ultra-minia-
ture SIP7 pin size. Devices are encapsulated using flame retardant resin.
High performance features include 1000VDC input/output isolation,
high efficiency operation and output voltage accuracy of ±±3 maxi-
mum. Standard features include an input range of ±103 tolerance and
low output ripple and noise.

Input filter components are required to help meet conducted emissions class B,
which application refer to the EMI filter of design & feature configuration.
** An external filter capacitor is required if the module has to meet IEC61000-4-4
and IEC61000-4-5.

Note:
1. Operation under minimum load will not damage the converter; However, they
may not meet all specification listed, and that will reduce the life of product.
2. All specifications measured at Ta=25°C, humidity<753, nominal input voltage
and rated output load unless otherwise specified.
