V
REF
:
Outputs the reference voltage
2.6 V (allowance: 3%)
Incorporating short-circuit protection
against ground.
2
RT:
Connection for the timing resistor which
decides the oscillator frequency. Use a re-
sistor in the range 5.1 k
to 30 k
. The
pin voltage is approx. 0.4 V.
3
CT:
Connection for the timing capacitor which
decides the oscillator frequency. Use a ca-
pacitor in the range 100 pF to 10 000 pF.
For the oscillator frequency setting, refer
to the "Application Notes, [1] Function
descriptions" section. Use an oscillator fre-
quency in the range 5 kHz to 500 kHz.

DTC:
Connection for a resistor and a capacitor
that set the dead-time and soft start period
of PWM output.
Input current I
DTC
is decided by the timing
resistor R
T
which controls sample to sample
variations and temperature variations.
It is approx.
