DC/DC Converters
TSR 0.5SM Series, 0.5 A Switching Regulator
Features
◆ Compact SMD package
◆ Very high efficiency up to 97%
◆ Excellent line / load regulation
◆ Low standby current
◆ Operating temperature range –40 to 90°C
◆ Over-temperature protection
◆ Remote On/Off input
◆ Adjustable output voltage
◆ Short circuit protection
◆ Moisture sensitivity level 2
as per IPC J-STD-020D.1
TSR-0.5SM is a series of step-down non–isolated switching regulators in compact
SIP package. These converters are an ideal alternative to LM78 linear regulators
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.
◆ꢀ3-year product warranty
Excellent output voltage accuracy and low standby current are other features that-
distinguish switching regulators from linear regulators.

1) For input voltage higher 24 VDC an input capacitor 22 µF/ 50 V is required
2) Input voltage must be higher than output voltage set:>1.5 V for 3.3–5.0V and >3 V for 6.5–15.0V
