3V to 13.2V Input • 0.5V to 5.5V Output
chassis ground trace (if applicable) must be capable
of conducting a current of 1.5 times the value of the
fuse without opening. The fuse must not be placed
in the grounded input line.
Abnormal and component failure tests were
conducted with the POL input protected by a fast-
acting 65 V, 15 A, fuse. If a fuse rated greater than
15 A is used, additional testing may be required.
In order for the output of the ZY7120 POL converter
to be considered as SELV (Safety Extra Low
Voltage), according to all IEC60950 based
standards, the input to the POL needs to be supplied
by an isolated secondary source providing a SELV
also.
