1 Phase AC Input: 5W 4 Rail Outputs Reference Design for E-meter
Texas Instruments
The reference design was designed for the 1 phase smart meter application. It uses the UCC28600 quasi-resonant flyback controller to generate four 3KV isolated output rails from an extremely wide input source from 85VAC to 300VAC. The four output rails have independent protections to improve system reliability. The synchronous buck converter TPS560430 was used on the 12V 0.3A rail to generate a 0.1% output ripple voltage for post modules. The board size is 100mm(L)*43.5mm(W)*20mm(H).
