DESCRIPTION
The DCV01 series is a family of 1W, 1500Vrms
isolated, unregulated, isolated DC/DC converters. Re-
quiring a minimum of external components and in-
cluding on-chip device protection, the DCV01 series
provides extra features such as output disable and
synchronization of switching frequencies.
The use of a highly integrated package design results
in highly reliable products with a power density of
40W/in
high isolation and small size makes the DCV01 suit-
able for a wide range of applications.

... DC/DC converter with inherently high reliability. ADDITIONAL FUNCTIONS IN DISABLE/ENABLE The DCV01 can be disabled or enabled by driving the SYNC pin using an open drain CMOS gate. If the SYNC pulled low, the DCV01 will be disabled. The disable time depends upon the external loading; the internal disable func- tion is implemented ...

... In order to avoid the supply falling momentarily during the fast switching pulses ground and power planes should be used to track the power to the input of DCV01. If this is not possible then the supplies must be connected in a star formation with the tracks made as wide as possible. ...
