DC/DC Converters

TSR 0.5 Series, 0.5 A Switching Regulator

Features

◆

Compact SIP package

◆ Very high efﬁciency up to 97%

◆ Excellent line / load regulation

◆ Low standby current

◆ Operating temperature range –40 to 90°C

◆ Over-temperature protection

◆ Short circuit protection

◆ 3-year product warranty

TSR-0.5 is a series of step-down non–isolated switching regulators in compact SIP

package. These converters are an ideal drop-in replacement to LM78 linear regu-

lators when energy efﬁciency is a parameter of the design. The high efﬁciency up

to 97 % allows full load operation up to +80°C (+90°C with 50% load) ambient

temperature without the need of forced aircooling.

Excellent output voltage accuracy and low standby current are other features that-

distinguish switching regulators from linear regulators.
