LME78_2.0 Series

Wide Input Non-Isolated & Regulated, Single Output

Switching Regulator

High eﬃciency up to 96%

Operating temperature range:

-40°C ~ +100°C

Short circuit protection (SCP)

High voltage input range, up

to 36V

3PIN SIP package

The LME78_2.0 are high eﬃciency switching regulators and ideal

substitutes of LM78xx series three-terminal linear regulators. The product

is featured with high eﬃciency, low loss, short circuit protection and no

heat sink requirement. They are widely used in industrial control, instru-

mentation, and electric power applications.

Note:

1. Do not operate exceeding the absolut maximum rating, it will cause damage;

2. Operation unter no-load conditions will not damage these devices, however

they may not meet all listed speciﬁcations;

PFMF

An external ﬁlter capacitor and TVS is required if the module has to meet

IEC61000-4-4 and IEC61000-4-5.

3. Unless otherwise speciﬁed, data in this datasheet should be tested under the

conditions of Ta = 25°C, humidity <75% when inputting nominal voltage and

outputting rated load;

4. All index testing methods in this datasheet are based on our Company’s

corporate standards;

Input reﬂected ripple current test step:

IOutput ripple & noise measurement test:

Measured with a 0.1µF ceramic capacitor. The scope measurement

bandwidth is 0-20MHz.

Input reﬂected ripple current ist measured through a source

indicator Lin (12µH) and a source capacitor Cin (10µF, ESR<1.0Ω at

100KHz) at nominal input and full load.

EMC countemeasures

EMI countermeasures

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

EMI requirement for the module. These components should be

mounted as close as possible to the module; and all leads should

be minimized to decrease radiated noise.
