BIAS 1 Watt Power Supply BPSX 1 Series Data Sheet Single (Vo) or Dual (Vo & Vr) output BPSX 1-08-00, -08-33, -08-50 BPSX 1-14-00, -14-33, -14-50 The BPSX is a revolutionary, micro-sized, drop-in switching power supply module. It contains patented technology with unique features that provide solutions for a wide range of applications, including low power wireless and many other intelligent control devices. The patented SMPS topology is totally different from any other: It's Quiet: Switching is synchronized and occurs only 10% of the time, so there is very little EMI / EMC interference with other circuits. This means no extra filtering or shielding is needed, helping to achieve longer transmission range with more reliable data communication in low power wireless applications. Actual Size Features: • • • • • • • • Extended Temperature with NO DE-RATING! (-40 to +85°C ) Universal Input (85-265 VAC, 50/60Hz) Small Size—0.55in3 [9.0cm3] Low no-load input power <30mW Constant power mode (not current limit) 3000 VAC Isolation EN 55022, Class B; FCC Part 15, Class B Meets UL/CSA and EN Product Safety (ITE) It's Powerful: No power de-rating across the full wide temperature range. No current limit design margin needed when selecting a module. Charge Bias Power AC/DC power supplies are available with two different types of outputs to fit your applications… large super caps faster than any regular SMPS with twice the power rating. The characteristics of the main (Vo) and auxiliary (Vr) outputs It's Green: High efficiency with ultra low standby power and very little self are different and each has application-specific benefits which generated heat make it ideal for intelligent devices such as smart-sensors, can provide high value to the system designer: smart-meters, smart-lighting, smart-grid, M2M or IoT , and any other control Vo is a voltage-regulated output which has a constant power applications.

This output is best suited as a source for isolated DC utility power, which may be used directly or post-regulated with either a linear regulator or a DC/DC converter. Vo is self protecting, cannot be overloaded and can be shorted indefinitely. So unlike design-yourown, or partially complete modules where significant design margin is required to stay far away from current limit, there is no need to oversize a Bias Power supply. The graceful transition from voltage regulation to constant power along with the wide range of product ratings allows the designer to select a supply tightly matched to the design load. Vr is also a voltage-regulated output and is thermally protected from overload. It has very low output ripple capable of driving elements which require a low-noise, tightly-regulated supply. In addition, Vr is supplied internally by Vo. This means that any capacitance added to Vo can increase the hold-up time of Vr as well. *Note: maximum currents specified for constant voltage range only.
