Device Output
Supply Voltage
Input voltage that determines output current.
Reference Ground for Input Voltage at Sense Input
Capacitor between this terminal and Sense Ground determines the
current slope dI

t
during off phase.
Low level at this input sets the device after a delay time t
in the
standby mode independent from control input (2nd priority) (in
standard applications pin 6 must be left unconnected).
High level at this input switches the BU508 off, low level switches
the BU508 on.
A high level at this input switches the BU508 off independent from
all other inputs (1st priority).
