Designed for standby mode and other low-power supply applications, the Bias Power BPSX Series micro-size switching power supply allow designers to easily solve space and efficiency problems.  Available in either ½ watt, 1 watt or 2 watt models, this new supply operates with nominal 75% efficiency and has an extremely small footprint. The BPSX is designed for a wider operating temperature range than the standard BPS and operates from -40 to +85 deg C without de-rating.

 Applications for the BPS are widespread, include powering remote and networked sensors, power-line carrier, relay drivers, test equipment, IR receivers, building automation, audio, video, security, AC power adapters and bias supplies.  It is ideal for standby mode applications in appliances and consumer electronics, providing power to system clocks, processors, IR remote receivers, membrane keypads and LED panel lighting.  With a no-load power consumption of less than 30 mW, the BPS series efficiently handles the widest possible load variations.

The Bias Power BPS is based on a patented* circuit design, that so effectively eliminates line EMI that no input filtering is required.  This is achieved by isolating the input path for the duration of the conducted noise. The circuit also maximizes conversion efficiency and effectively regulates output voltages, even over 85 to 265 VAC. Single outputs of 8V, 14V, 24V and dual outputs of 8V/3.3V, 8V/5V, 14V/3.3V and 14V/5V are available.  An attribute of the overall assembly is extremely rugged construction, making the BPS well suited for portable and harsh environment applications.  The BPS is a ready-to-apply solution, so there’s no need to re-invent the wheel with larger home-grown switchers.
