Notes:
1. Specified with a C4 (see typical connection diagram at right) value of
22 uF/400V. A high frequency, low impedance electrolytic capacitor should
be used.
2. Load regulation is measured for an output change of 10% to 90% at nominal
input line. For multiple output models, the loads are balanced.
3. The unit will shut down when the over temperature protection is triggered. The
unit will restart when the ambient operating temperature falls below 85ºC.
4. It is recommended that a fuse be used on the input of a power supply for
protection. For the MPS-03 series, a 0.5A/250 VAC slow blow should be
used.
The diagram above illustrates a typical application connection of the MPS-03 series. The
Derating Curve top diagram illustrates a DC/DC converter connection while the bottom diagram show the
unit connected as an AC/DC power supply. Notes on these circuits are:
1. To maintain clearance and creepage distances (for Class I & Class II devices) the board
layout should guarantee the following spacing between the L and N inputs (before the
fuse):
Clearance - 2 mm
Creepage - 2.5 mm
2. The recommended fuse is a 0.5A/250V slow blow.
3. For EMI sensitive applications, the input filtering circuit (inside the dotted boxes of the
AC circuit) may be added. The filter consists of:
Cx: Capacitor C1 is 0.1 µF/275V
CY: Capacitors C2 and C3 are 220 pF/2000V
T1: Common mode choke, UU9.8 or ring core. Inductance is
about 10 mH to 30 mH & wire diameter of 0.22 mm.
4. The MOV is required for surge protection. C5 C6
Recommended is a 471KD07. VOUT TVS
(µF/V) (µF/V)
5. The input storage capacitor (C4) is a low ESR 3.3 150/25 0.1/50 P4KE6.8A
electrolytic with a rating of 22 µF /400V. This 5.0 150/25 0.1/50 P4KE6.8A
capacitor must be used for operation with an 9.0 150/25 0.1/50 P4KE12A
AC input.
12.0 150/25 0.1/50 P4KE20A
6. The output filtering capacitor (C5) is a high
Mechanical Dimensions frequency, low resistance electrolytic capacitor. 15.0 100/35 0.1/50 P4KE20A
A ceramic capacitor (C6) is used to filter high 24.0 100/35 0.1/50 P4KE33A
frequency noise. Recommended values are
given in the table at right.
7. The TVS is recommended to protect application circuitry in the event of a fault. Recom-
mended values are given in the table above.
