PowerPax UK Ltd launches a range of ultra miniature PCB mounting switch mode power supplies

Believed to be the smallest, fully functional switch mode power supply available, the BPS product series is available in output powers of 0.5W, 1.0W and 2.0W. With proven reliability this product range provides a complete solution that enables designers to reduce the engineering cycle, simplify certification and therefore reduce time to market whilst also allowing engineers to concentrate on their core competencies.

The Bias Power BPS series is based on a patented circuit design that effectively eliminates line EMI so that no input filtering is required. This is achieved by isolating the input path for the duration of the conducted noise. The circuit design ensures that conversion efficiency is maximized and effectively regulates output voltages evenly over the entire 85 to 265 VAC input range. Single outputs of 8 & 14V DC and dual outputs of 8 & 5 VDC are available. The range features efficiencies of up to 75%, an operating temperature range of -25 to +70ºC (-40 to +85Cº optional), full short circuit protection and input to output isolation of 3KVAC. This series offers an extremely small footprint of 22.73 x 26.29 x 13.56mm (8cm3) in a rugged tamper-proof sealed package ensuring that PCB real estate usage is maximized.

These products are UL, cUL and CE approved and comply to the RoHS directive.

The BPS series meets EMC requirements without the need for additional components and its low emissions characteristics make it particularly suitable for ZigBee IEEE (802.15.4), Z-wave, Bluetooth GSM, GPRS and other emissions critical applications. This range is also suitable for other demanding applications such as the charging of super capacitors, security systems, standby power and lighting occupancy sensors.

The BPS range offers a ready-to-apply solution, so there’s no need to re-invent the wheel with larger home-grown switchers. In addition to this full technical support is offered with direct contact to the engineers who designed this series.
