FEEDBACK Pin Auto-Restart Threshold Voltage V FB(AR) T J = 25 °C 0.8 V Auto-Restart ON-Time V FB = VFB(AR) T J = 25 °C 100 ms Auto-Restart Duty Cycle DC AR 12 % NOTES: A. In a scheme using a resistor divider network at the FB pin, where R U is the resistor from the FB pin to the rectified bias voltage and R L is the resistor from the FB pin to the SOURCE pin, the output voltage variation is influenced by V FB and IFB variations. To determine the contribution from the VFB variation in percent, the following equation can be used: To determine the contribution from I FB variation in percent, the following equation can be used: Since I FB and VFB are independent parameters, the composite variation in percent would be . B. Total current consumption is the sum of I S1 and IDSS when FEEDBACK pin voltage is ≥2 V (MOSFET not switching) and the sum of I S2 and IDSS when FEEDBACK pin is shorted to SOURCE (MOSFET switching). C Since the output MOSFET is switching, it is difficult to isolate the switching current from the supply current at the DRAIN. An alternative is to measure the BYPASS pin current at 6 V. D. See Typical Performance Characteristics section Figure 15 for BYPASS pin start-up charging waveform. E. This current is only intended to supply an optional optocoupler connected between the BYPASS and FEEDBACK pins and not any other external circuitry. F. This parameter is guaranteed by design. G. This parameter is derived from characterization. H. Breakdown voltage may be checked against minimum BV DSS by ramping the DRAIN pin voltage up to but not exceeding minimum BV DSS.
