5V
15V
VT (3.5 to 6V)
Startup circuit turns
on when VCC reaches
the threshold VT
8.1V
Maximum drain current is
limited to 1.15V / Rsense
0A
Startup circuit is
charging the VCC
capacitor
Vref regulator turns on
when VCC reaches 15V
Switching starts when
Vref reaches 5V
Switching stops when
Vref falls below 3.7V
Reference Voltage, Vref
Drain Current
Vref falls faster than VCC
since Vref capacitor is much
smaller than VCC capacitor
Supply Voltage, VCC
Vref regulator turns
off when VCC falls
below 8.1 V
Startup circuit turns
off when VCC is 15V
