DC/DC Converters

THM 3WI Series, 3 Watt

Features

◆

Ultra wide 4:1 input voltage

◆ I/O isolation 5000 VACrms rated for

250 VACrms working voltage

◆ 2 x MOPP Medical safety according to

AAMI/ANSI ES 60601-1:2005(R) and

IEC/EN 60601-1 3rd edition

◆ Low leakage current <2 µA

◆ Very high efﬁciency up to 87%

◆ Extended operating temperature range

–40°C to 94°C at full load.

◆ Input ﬁlter to meet EN55022 class A

◆ 3-year product warranty

The THM-3WI series is a range of high performance, regulated 3 Watt DC/DC

converters in a DIP-24 plastic package. The reinforced I/O-isolation system com-

plies with the medical safety requirements for MOPP (Means Of Patient Protection).

Together with a wide 4:1 input voltage range, and an internal EMI ﬁlter to meet

EN55022 class A the converters constitute also a reliable solution for many de-

manding applications such as transportation systems, industrial control equipments,

measurement equipments, and some IGBT driver applications. With A high efﬁcien-

cy of up to 87% and highest grade components the converters can reliably operate

in an ambient temperature range of –40 up to +94°C at full load.
