The series can meet EN55032 Class B with an external ﬁlter in parallel with

the input pins.

** An external ﬁlter is required if the module has to meet IEC61000-4-4 &

IEC61000-4-5.

Measured through a source indicator L1 (12µH) and a source capacitor C1=10µF

at nominal input and full load.

** The remote ON/OFF pin is referenced to GND.

Note:

Example:

1. All speciﬁcations measured at Ta = 25°C, humidity <75%, nominal input voltage

and rated output load unless otherwise speciﬁed.

Typical characteristics

The switching frequency is diﬀerent according to

output voltage models.

Test conﬁgurations

Input reﬂected ripple current test step

Input reﬂected ripple current is measured though a source

inductor Lin (12µH) and a source capacitor Cin (10µF,

ESR<1.0Ω at 100KHz) at nominal input and full load.

Output ripple & noise measurement test

Use a capacitor Cout (1.0µF) measurement.

The scope measurement bandwidth ist 0-20MHz.

LMTOW78_0.5 series

Wide input, non-isolated & regulated, single output, SMD package

Design conﬁgurations

Remote ON/OFF test step

Input ﬁlter components (C1, C2, L1, C3, C4) are used to help

meet conducted emissions requirement for the module.

These components should be mounted as close as possible

to the module; and all leads should be minimized to decre-

ase radiated noise.

Output voltage adjustment

Pin 6 via a resistor to +Vout (pin5), Vo trim down.

Pin 6 via a resistor to GND (pin 7), Vo trim up.

Standard application circuit

Note:

1. Cin is required and must be connected close to the pin terminal of the

module. (Cin=10µF).

2. Cout= 10µF (optional)

EMC countermeasures

EMI countermeasures

Input ﬁlter components (C1, C2, L1, C3, C4) are used to help

meet conducted emissions requirement for the module.

These components should be mounted as close as possible

to the module; and all leads should be minimized to decre-

ase radiated noise.

EFT & Surge test countermeasures

The ﬁlter we suggest: Nippon - chemi - con KY series,

330µF/100V and TVS, 3KW, 70V
