DT2:
The pin for setting channel 2 output maximum
duty ratio.
If this terminal is set at a voltage of 0.9 V or more,
FB2 terminal becomes high-level voltage and the
protective function for channel 2 output short-
circuit will stop (Unlatch function).
FB2:
The output pin for error amplifier 2 block.
The source current is 47 A and the sink current
is 47 A.
Correct the frequency characteristics of the gain
and the phase by connecting a resistor and a ca-
pacitor between this terminal and GND.
IN 2:
The noninverting input pin for error amplifier 2
block.
Off:
The terminal for on/off control.
High-level input: Normal operation (V
V)
Low-level input: Standby state (V
The total current consumption in the standby state
can be suppressed to a value 1 mA or less.

The output terminal for the internal reference
voltage.
The reference voltage is 1.19 V (allowance: 2%) at
