Pin No. Equivalent circuit Description I/O
1 CT: O
The terminal used for connecting a timing
capacitor to set oscillator frequency. Use a
capacitance value within the range of 100 pF
to 0.1 mF. For frequency setting method,
refer to the "Application Notes, [2] Function
descriptions" section. Use the oscillation fre-
quency in the range of 1 kHz to 500 kHz.
2 RT: I
The terminal used for connecting a timing
resistor to set oscillation frequency.
Use a resistance value ranging from 5.1 kΩ
to 20 kΩ.
The terminal voltage is 0.67 V typ.
3 On/Off: I
The terminal for on/off control.
High-level input: normal operation
(V
ON/OFF
> 2.0 V typ.)
Low-level input: standby state
(V
ON/OFF
< 0.8 V typ.)
The total current consumption in the standby
state can be suppressed to a value below 5 µA.
4IN−2: I
The terminal for the inverted input of ch.2
error amplifier. Use a common-mode input
ranging from − 0.1 V to 0.8 V.

5 FB2: O
The output terminal of ch.2 error amplifier.
Its source current is −25 µA typ. and sink
current is 8 mA typ.
Correct the frequency characteristics of the
gain and the phase by connecting a resistor
and a capacitor between the terminal and
IN−2 terminal.
6 DTC2: I
1) Terminal for connecting a resistor and a
capacitor for setting the dead-time and the
soft start period of ch.2 PWM output.
Input current I
DTC
is determined by the tim-
ing resistor RT so that dispersion, and fluc-
tuation with temperature are suppressed. The
input current is −35 µA typ.

ing the terminal voltage to below 0.12 V.
(short-circuit protection function stop)
7 Out2: O
The ch.2 open-collector type (Darlington)
output terminal.
The absolute maximum rating of output cur-
rent is 150 mA.
Use with an output current under 100 mA
normally.
