Wide Input 2W Bias Power Supply
Description
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.
Features
- 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
