Open collector type output pin with an emitter connected to
GND.
Output current may be up to 50 mA.
Ground pin
Open collector type output pin with an emitter connected to
GND. Output current may be up to 50 mA.
Used to set OUT2 pin dead time. V
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.
Error amplifier 2 output pin: connect resistor and capacitor
between this pin and the –IN2 pin to set gain and adjust
frequency characteristics.
Error amplifier 2 inverting input pin.
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 “
the Time Constant for the Timer-Latch Type Short Prevention
Circuit.”
Open collector type output pin for emitter connected to GND.
Output current may be up to 50 mA.
Used to set OUT3 pin dead time. V
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.
Error amplifier 3 output pin: connect resistor and capacitor
between this pin and the –IN3 pin to set gain and adjust
frequency characteristics.
Error amplifier 3 inverting input pin.
Power supply control pin: low level places the IC in standby
mode and reduces power consumption to 10 µA or lower. Input
level may be driven by TTL or CMOS.
Power supply pin: voltage range is 3.6 V to 18 V.
