Description
I/O
1
OSC:
O
The terminal used for connecting a timing capaci-
tor/resistor to set oscillation frequency.
Use a capacitance value within the range of 100 pF
to 10 000 pF and a resistance value within the range
of 3 k
Ω to 30 kΩ. Use an oscillation frequency in the
range of 20 kHz to 1 MHz. When operating the
circuit in parallel and synchronously, the channel 2
output stops when this pin becomes 0.9 V or more.
(Refer to the "Application Notes, [7]" section.)
2
S.C.P.:
O
The terminal for connecting a capacitor to set the
time constant of the timer latch short-circuit pro-
tection circuit. Use a capacitance value in the range
of 1 000 pF or more. The charge current ICHG is
1.1
µA typical.
3IN
+1:
I
The noninverting input pin for error amplifier 1
block.
4IN
−1:
I
The inverting input pin for error amplifier 1 block.
5
FB1:
O
The output pin for error amplifier 1 block.
The source current is
−47 µA and the sink current
is 47
µA.
Correct the frequency characteristics of the gain
and the phase by connecting a resistor and a capa-
citor between this terminal and GND.
