BCM4414XD1E5135YZZ Datasheet, PDF (11/41 Pages) Vicor Corporation – Isolated Fixed-Ratio DC-DC Converter

BCM4414xD1E5135yzz
Serial Clock input (SCL) AND Serial Data (SDA) Pins
• High power SMBus specification and SMBus physical layer compatible. Note that optional SMBALERT# is signal not supported.
• PMBus^TM command compatible.
• The internal µC requires the use of a flip-flop to drive SSTOP. See system diagram section for more details.
