LMTO78_12-0.5 数据手册

LMTO78_0.5 Series

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

Switching Regulator

Eﬃciency up to 95%

Short circuit protection (SCP)

No-load input current as low

as 0.2mA

The LMTO78_0.5 Series are high eﬃciency switching regulators. The

converters feature high eﬃciency, low loss and short-circuit protection

in a compact SMD package. These products are widely used in applica-

tions such as industrial control, instrumentation and electric power.

The “parallel cable” method is used for Ripple and Noise test, please refer to

DC-DC Converter Application Notes for speciﬁc information.

With light loads at or below 20%, Ripple & Noise for 3.3V output parts increases

to 100mVp-p max, and a load below 10% for 5V/9V/12V/15V output parts levels

increase to 150mVp-p max.
