Wide Input 2W Bias Power Supply (PMP7668)

This reference design is a 2W bias power supply for applications requiring operation over a wide input range (110 - 500VAC). The small form factor (69mm x 26mm) and high efficiency of this design make it ideal for e-metering applications. Information provided in this design will reduce time to market by providing important test data such as efficiency, output ripple, startup, and switching stress. Additionally, TI has conducted emissions testing on this design to ensure that it exceeds the EN55022 Class B limits.


Supports a wide input voltage range: 110VAC - 500VAC Targeted for small form factor applications (69mm x 26mm) Greater than 65% efficiency over tested operating range Achieved voltage regulation of +/-1% at full load Test results demonstrate this design's capability to pass EN55022 Class B EMC standard
