For applications that require meeting higher EMC standards,

the circuit shown at left is recommended. Some notes on this

diagram (starting with the input circuit) are:

1. It is recommended that an external fuse be used. The

recommended fuse is 15A/1,500V.

2. Capacitors C1, C2, C3 and C4 are input ﬁlter components

(connected in series to achieve the required capacitance

level).

3. Capacitors C5, C6, C7 and C8 are also input ﬁlter com-

ponents. Resistors R1, R2, R3 and R4 help to balance the

current across the capacitors.

4. Capacitor C9 is ceramic. This capacitor is used to ﬁlter

high frequency noise. A recommended value is given in

the table below.

5. Capacitor C10 is an electrolytic. A low ESR, high frequency

capacitor should be used.The recommended value is given

in the table below.

6. The output TVS will help protect system circuitry if the

converter fails.A recommended value is given in the table

below.

7. Derating on all capacitors should be 80% or more.

The diagram at left illustrates a typical connection of the

MPV4080S-xxRHI series. Output capacitors C9 and

C10 are ﬁltering components. Capacitor C9 is a ceramic

and C10 is a high frequency, low resistance electrolytic.

The TVS is recommended to protect circuit components if

there is a fault with the converter.

The recommended component values are given in the

table below.
