BCM3814B60E10A5C02 Datasheet, PDF (11/38 Pages) Vicor Corporation – Isolated, Fixed-Ratio DC-DC Converter

BCM3814x60E10A5yzz
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.
