Functional Description Start up An internal start up diode is connected between pin PCS and pin V via this diode higher than V PCS During start up the internal reference of the IC is shut off and ...

Page 7

Soft start The internal reference of the IC is switched on when V begins to work with soft start mode. Soft start is realized with an internal soft start resistor, an inter- nal current sink, a current source and the ...
