Oscillator Resistor R ROSC
The oscillator frequency is programmable from 100kHz to 540kHZ with an external resistor R ROSC as shown in Figure 6.
The oscillator generates an internal 50% duty cycle saw tooth signal (Figure 4.) that is used to generate 180° out-of-phase
timing pulses to set Phase 1 and 2 RS flip-flops. Once the switching frequency is chosen, R ROSC can be determined from
the curve in the I(SETBIAS) vs. Rosc curve in the Typical Operating Characteristics Section.
Soft Start, Over-Current Fault Delay, and Hiccup Mode
The IR3092 has a programmable soft-start function to limit the surge current during converter power-up. A capacitor
connected between the SS/DEL and LGND pins controls soft start timing as well as over-current protection delay and
hiccup mode timing.
Figure 8 depicts the various operating modes of the SS/DEL function. Under a no fault condition, the SS/DEL capacitor
will charge. The SS/DEL charge soft-start duration is controlled by a 55uA charge current which charges CSS up to 4.0V.
The Error Amplifier output is clamped low until SS/DEL reaches 1.3V. The Error Amplifier will then regulate the
converter’s output voltage to match the SS/DEL voltage less the 1.3V offset until it reaches the level determined by the
VID inputs. The PWRGD signal is asserted once the SS/DEL voltage exceeds 3.75V.
