Description
8
VOUT1
O
Open collector type output pin with an emitter connected to
GND.
Output current may be up to 50 mA.
9
GND
—
Ground pin
10
OUT2
O
Open collector type output pin with an emitter connected to
GND. Output current may be up to 50 mA.
11
DTC2*
1
I
Used to set OUT2 pin dead time. V
REF
voltage is divided by an
external resistor and applied to set dead time. Also, a capacitor
may be connected between this pin and the GND pin to
perform soft start operations.
12
FB2
O
Error amplifier 2 output pin: connect resistor and capacitor
between this pin and the –IN2 pin to set gain and adjust
frequency characteristics.
13
–IN2
I
Error amplifier 2 inverting input pin.
14
SCP*
2
—
Time constant setting capacitor connection for timer-latch
type short prevention circuit: a capacitor should be connected
between this pin and the GND pin. For details, see “
I
Setting
the Time Constant for the Timer-Latch Type Short Prevention
Circuit.”
15
OUT3
O
Open collector type output pin for emitter connected to GND.
Output current may be up to 50 mA.
16
DTC3*
1
I
Used to set OUT3 pin dead time. V
REF
voltage is divided by an
external resistor and applied to set dead time. Also, a capacitor
may be connected between this pin and the GND pin to
perform soft start operations.
17
FB3
O
Error amplifier 3 output pin: connect resistor and capacitor
between this pin and the –IN3 pin to set gain and adjust
frequency characteristics.
18
–IN3
I
Error amplifier 3 inverting input pin.
19
CTL
I
Power supply control pin: low level places the IC in standby
mode and reduces power consumption to 10
μ
A or lower. Input
level may be driven by TTL or CMOS.
20
V
CC
—
Power supply pin: voltage range is 3.6 to 18 V.
