ZHCS573I August 2010 – April 2018 LM25119
PRODUCTION DATA.
EN2 is left floating which allows channel2 to always remain enabled. If EN2 is pulled below 2 V, channel2 is disabled.
The DEMB pin is left floating because the design sample uses diode emulation. For fully synchronous (continuous conduction) operation, connect the DEMB to a voltage greater than 2.6 V.
VCCDIS is left floating to enable the internal VCC regulators. To disable the internal VCC regulators, connect this pin to a voltage greater than 1.25 V.
