=10mA, Topt=25C, and use External Circuit of Typical
Application (FIG. 1).
(Note 1) Soft-Start Circuit is operated in the following sequence :
(1) V
IN
is applied.
(2) The voltage (Vref) of the reference voltage unit is maintained at 0V for about 200μs after the application of V
IN
.
(3) The output of Error Amp. is raised to “H” level during the maintenance of the voltage (Vref) of the reference voltage unit.
(4) After the rise of Vref, the output of Internal Error Amp. is gradually decreased to an appropriate value by the function of Internal Phase
Compensation Circuit, and the Output Voltage is gradually increased in accordance with the gradual decrease of the output of Internal Error
Amp.
(Note 2) I
LX
is gradually increased after Lx Switch is turned ON. In accordance with the increase of I
LX
, V
LX
is also increased. When V
LX
reaches V

lim
,
Lx Switch is turned OFF by an Lx Switch Protection Circuit.
