Non-Isolated DC/DC Converter (POL)
• Ultra wide 8:1 input voltage range:
9-72 VDC
• Covers a majority of standard bus- and
battery voltages
Up to 93% efficiency - No heatsink
required

The TSR 1WI is a non-isolated POL converter series with an ultra wide 8:1 input
voltage range which comes in a standard SIP-3 package. Covering the majority
of standard bus- and battery voltages this POL converter is a versatile solution
for many applications in distributed power systems where different input volt-
ages have to be handled. Being able to use the same converter in many differ-
ent situations effectively reduces the bill of material (BOM) of a given applica-
tion. A high efficiency of up to 93% allows for an operating temperature range
of -40 to +80°C (up to 50°C without derating) and makes them excellent
drop-in replacements for less efficient LMxx linear regulators. With 0.6A max.
output current and standard features such as low standby current, precise reg-
ulation and protection against short circuit, overvoltage and overload the TSR
1WI is suitable for many battery and distributed power applications.
