The recommended transformer meets the isolation
(creepage and clearance) requirements for BASIC
insulation according to IEC60950, for input voltage
ranges of 24 V, 48 V or 60 V nominal (100 V
transient). To ensure that the complete card meets
this requirement, the brick used for the intermediate
bus and the optocouplers used for isolation must
meet the same requirements. The PCB must
maintain adequate spacing between primary and
secondary for all components and copper traces. It
is recommended to provide an isolation barrier in
the PCB which is free of copper traces on all layers
(including
ground
planes),
with
a
width
of
approximately 0.1 inches (0.062 inches minimum).
Refer to AN-4 —Designing On-Card Power Circuits
for more details.
Applications information
This section provides information on component
selection, as well as some information on using
additional features of the Tsi206. Refer to Figure 1
on page 1 for the typical application circuit.
Powering the Tsi206
The Tsi206 contains an internal shunt regulator on
the VDD pin that prevents the voltage on that pin
from exceeding 3.3 V. It is necessary to use an
external resistor Rd (R5 in Figure 1) between the
card supply voltage and the VDD pin. The resistor
allows the device to operate across a wide range of
