BPS Series miniature isolated DC/DC converters

Now with output to 300 VDC

BPS Series high-voltage DC-DC converters feature up to five times better efficiency and ten times better load regulation than similar products on the market.

These are configurable 1.5W converters, ideal for powering PIN diodes, APDs and piezoelectric devices.  Applications include RF transcievers, programmable filters, and industrial or scientific instruments.

These high-reliability isolated converters operate from -55°C to +85°C with no heat sink or electrical derating required.

The ultra-miniature encapsulated package is only 0.4" (10.2 mm) tall, with a total 0.1 cubic inches and weight of just 4 grams. Both through-hole and SMT versions are available.

BPS Series converters have a single input voltage (configurable from 3 VDC to 15 VDC) and a single output voltage (configurable from 50 VDC to 300 VDC). They are unregulated; output voltage is directly proportional to input voltage.

See typical characteristics below, or download the data sheet with drawings (347Kb PDF).
