Description:
M57184N-715 is a non-isolated
step down DC-to-DC conver ter
designed to take direct input
of 140 ~ 360VDC and provide
2 outputs. One output is
+15V/350mA and the other is
rated at +5V/200mA. This
converter allows use of fewer
exter nal components than does
a combination of electrolytic
capacitors and choke coils only.
Features:
□Input Voltage Range
DC 140V ~ 360V
□Output Specifications
15V, 350mA and
5V, 200mA
Applications:
□Power Source for DIP IPMs
and ASIPMs
□Home Appliances
□Industrial Controls

Inductor for Application Example Circuit
1. Recommended Inductors
Manufacturer Part Number
Mitsumi C13-FR Series, Type # GA 102
API Delevan 4590-105K
J.W. Miller 5900-102
2. Specifications for Inductor
We recommend an inductor with these specifications: an inductance of 1mH, rated current of at least 500mA,
and good performance with DC superimposition. Please note there must be no magnetic saturation in the
inductor.
The following waveforms show the output ripple voltage on VO-1 for good versus bad inductors. These
waveforms are produced with output VO-2 unloaded and the scope coupleing set to AC.
