1.5W mini DC/DC converter offers 90% efficiency and tight load regulation

BEAR Power Supplies introduces its BPS Series high-voltage DC/DC converters, featuring up to five times better efficiency and ten times better load regulation than similar products on the market. These high-reliability isolated 1.5W converters are ideal for powering PIN diodes and APDs in applications such as RF transceivers, programmable filters, and industrial and scientific instruments.

The ultra-miniature encapsulated package measures 0.5 x 0.5 x 0.4 inches (12.7 x 12.7 x 10.2 mm) and weighs 4 grams. Both through-hole and SMT versions are available. BPS Series converters have a single input voltage (configurable from 3 VDC to 12 VDC) and a single output voltage (configurable from 50 VDC to 220 VDC). They operate from -55°C to +85°C with no heat sink or electrical derating required. Price is from $65 in volume.

BPS series typical characteristics
Input voltage — Single input, configurable from 3 VDC to 12 VDC
Output voltage — Single output, configurable from 50 VDC to 220 VDC
Line regulation — unregulated: output directly proportional to input
Load regulation — 3% change from no load to full load
Efficiency — 90% typical
Input voltage range — ±10% of specified input voltage
Output voltage tolerance at full load — Input +/- 3% (tighter tolerance available; consult factory)
Input/output isolation — 100 MΩ minimum at 1000 VDC
Output temperature coefficient — 0.02% per degree C for all models
Operating temperature — -55°C to +85°C ambient – no heat sink required
Storage temperature — -55°C to +125°C
Dimensions — 0.5 x 0.5 x 0.4 inches (12.7 x 12.7 x 10.2 mm)
