IN :
Error amplifier inverting input.
S.C.P.:
Connection for the capacitor that sets the
timer latch short-circuit protection circuit time
constant. Use a capacitor with a value of
1 000 pF or higher.
The charge current I
However, the capacitor is charged with a time
constant determined by 0.23 V and a resistance
of 6 k until the pin voltage reaches 0.23 V.
SS:
Connection pin for the capacitor that determines
the PWM output soft start period. Note that the
the short-circuit protection circuit does not
supply charge current to S.C.P. pin until this pin
voltage reaches about 0.2 V.
The source current I
However, the capacitor is charged with a time
constant determined by 0.23 V and a resistor of
6 k until the pin voltage reaches 0.23 V.
Off:
This pin controls the on/off for the IC.
High-level input: normal operation
(V
Low-level input: standby mode
(V
In the standby state, the total IC current
consumption is decreased to 5 A or under.
