Efficient, Low Noise DC/DC Converters Save Space

It’s not often you come across a power supply with both ultra low noise and high efficiency—you usually have to trade off one for the other. With our new TLB5 series of DC/DC converters, you get both, along with many other compelling features. Let’s take a closer look.

Low noise, high efficiency. At Polytron, we’ve designed and tested the TLB5 series for extra low noise. These DC/DC converters have an output ripple and noise of just 10 millivolts, thanks to a built-in EN55022 Class B filter for reducing electromagnetic interference.

In addition to the low noise, our TLB5 power supplies are highly efficient. While other models have efficiency rates in the low 80 percent range, this series tops out at 89 percent efficiency.

Space-efficient too. There’s another aspect of efficiency worth noting: the TLB5 ser ies saves space in your device. In many 2.5-watt single output applications, it’s common practice to double up a 2.5-watt power supply to meet the power requirements. With our 5-watt series, you can meet the same requirements with one small, compact DIP package of 1.25 x 0.80 x 0.40 inches.

Additional features. The TLB5 series has a wide operating temperature range up to 85°C and an input to output isolation voltage of 1600 volts. Other features include over current, short circuit, under voltage and over voltage protection, and a 4:1 wide input voltage range. This series also meets UL60950-1, EN60950-1 and IEC60950-1 safety standards. Some common applications include:

Telecommunications.
Data communications.
Measurement equipment.
Wireless network equipment.
Industrial control systems.
Semiconductor equipment.
