Out1:
The ch.1 open collector type (darlington)
output terminal.
The absolute maximum rating of output cur-
rent is 150 mA.
Use with an output current of 100 mA or less
normally.
DTC1:
1) Terminal for connecting a resistor and a
capacitor for setting the dead-time and the soft
start period of ch.1 PWM output.
Input current I
ing resistor RT so that dispersion and fluctu-
ation with temperature are suppressed. The
input current is 35 A typ, when R

2) The ch.1 output can be turned off by reduc-
ing the terminal voltage to below 0.12 V.
(short-circuit protection function stop)
FB1:
The output terminal of ch.1 error amplifier.
Its source current is 25 A 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 1 terminal.
IN 1:
The terminal for the inverted input of ch.1
error amplifier. Use a common-mode input
ranging from
