REFXDPL8219U40WTOBO1

REF-XDPL8219-U40W is a digitally configurable front-stage HPF flyback converter with a secondary-side regulated (SSR) constant-voltage (CV) output of 54V. An isolated UART reporting evaluation plug-in board is also included in this reference design packaging box. This plug-in board has an isolated uni-directional UART circuit, which can be evaluated optionally, by connecting it to the REF-XDPL8219-U40W.

• Secondary-side regulated (SSR) constant voltage (CV) output
• Supports universal input with 90Vrms to 305Vrms and DC input with 127V to 432V
• HPF and low iTHD, AC i/p voltage range (120 to 277Vrms) & o/p load range (33% to 100% of full load)
• High efficiency with quasi-resonant mode, QRMn, across wide input and output load range
• No-load standby power, as low as less than 100mW with active burst mode (ABM)
• Input overvoltage protection (OVP) and input undervoltage protection (UVP)
• Power limitation during brown-out, to better protect primary components
• Output and VCC OVP, under feedback open condition
• Output short protection
