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-

EFT & Surge test countermeasures
The filter we suggest: Nippon - chemi - con KY series,
330µF/100V and TVS, 3KW, 70V
