DC/DC Converters

TSR-1SM Series, 1 A

Features

◆ SMD-package

◆ Up to 96 % efﬁciency

◆ No thermal layer required

◆ Built in ﬁlter capacitors

◆ Operation temp. range –40°C to +85°C

◆ Short circuit protection

◆ Wide input operating range

◆ Excellent line / load regulation

◆ Low standby current

The new TSR-1SM series models of step-down switching regulators have a high ef-

ﬁciency up to 96 % which allows full load operation up to +65°C ambient tempera-

ture without the need of any heat transmission layer.

Excellent output voltage accuracy ( 2%) and low standby current (~1 µA) are fea-

tures that distinguish these switching regulators from linear regulators.

◆ 3-year product warranty
