Figure 1 Timer-Latch Short Circuit Protection Circuit
Figure 2 Timing Resistance/Oscillator Frequency Characteristics
4. Triangle Wave Oscillator Block
The triangle wave oscillator generates an essentially symmetric triangle wave using a timing capacitor and resistor
attached to the C
T
pin (pin 1) and the R
T
pin (pin 2), respectively. The voltage amplitude is between 1.4 and 2.0 V
with pin 2 stabilized at 1 V. The oscillator frequency is determined by the external capacitor and resistor.
5. Idle Period Adjustment Circuit Block
The idle period adjustment circuit consists of PWM comparators 1 and 2, each of which has one non-inverting and
two inverting inputs. The output pulse width (on time) is controlled according to the input voltage. Pins 6 and 11 are
dead time control pins, and are used to limit the maximum value of the pulse width. A pin voltage of 2.05 V
(Typical) or over results in the output being off for the whole period, and a pin voltage of 1.45 V (Typical) or lower
results in the output being on for the whole period.
