Mini DC/DC Converters provide up to 300 V output.

Press Release Summary:

Operating from -55 to +85°C with no heat sink or electrical derating, BPS Series includes single-input, single-output isolated converters with input voltage from 3-15 Vdc and output voltage from 50-300 Vdc. Units offer typical efficiency of 90% and are suited for powering PIN diodes, avalanche photodiodes, and piezoelectric actuators. Housed in encapsulated package measuring 0.5 x 0.5 x 0.4 in., converters are available in through-hole and SMT versions.

Original Press Release:

1.5W Mini DC/DC Converter Now Has Output to 300 Volts

Now with wider input and output voltage ranges, the BPS series isolated converters offer high efficiency and load regulation

July 9, 2007 - Phelps, NY - BEAR Power Supplies ( today announced higher voltage options for its 1.5W BPS series configurable DC/DC converters. These single-input, single-output isolated converters are now available with input voltage from 3 to 15 VDC and output voltage from 50 to 300 VDC. (The previous maximum input and output were 12 VDC and 220 VDC respectively.)

The BPS series converters feature up to five times better efficiency and ten times better load regulation than similar products on the market. They operate from -55°C to +85°C with no heat sink or electrical derating required. They are ideal for powering PIN diodes, avalanche photodiodes and piezoelectric actuators in applications such as RF transceivers, programmable filters, and industrial and scientific instruments.

The encapsulated package is only 0.5 x 0.5 x 0.4 inches (12.7 x 12.7 x 10.2 mm), and weighs just 4 grams. Both through-hole and SMT versions are available.
