Reversed Connection of Input
An error of reverse (＋,−electrodes) input may cause of
damage of the power module. If there is possibility to con-
nect the module conversely by accident, it is necessary to
attach a protective diode and an input fuse.
The rating voltage of the diode shall be higher than input
voltage, and the maximum in-rush current shall be higher
than fuse.
2 Output Voltage Range
Output voltage can be adjusted within±10% (3.3V, 5V,
the external trimmer (variable resistor). However, if the out-
put voltage become over the above range, OVP activates.
There is a limit of input voltage shown in Figure2-1 when
the output voltage trims high.

Connection method of external resistor (R1) and variable
resistor (VR) is shown as follow.

3 Maximum Output Ripple and Noise
Maximum output ripple and noise is measured by a method
based on JEITA-9141.
The connection is shown as Figure3-1. Attach capacitors
(C4: Ceramic Capacitor: 2.2μF, C5: Electrolytic Capaci-
tor: Refer to Table1-2) 50mm from the output for PH300S
and as short as possible to the output terminal for PH600.
Also, attach a coaxial cable with JEITA attachment at the
both side of C4 capacitor shown as Figure3-1. Oscillo-
scope shall be used at a range of 100MHz bandwidth.
The output ripple voltage and the output spike noise volt-
age may be changed for the design of printed circuit board.
For 48V output model, avoid to reduce the output voltage
below -10% cause damage of the module
