5 / 27 page 5 © 2007 Semtech Corp. www.semtech.com SC411 POWER MANAGEMENT Notes: 1) When the inductor is in continuous and discontinuous conduction mode, the output voltage will have a DC regulation level higher than the error-comparator threshold by 50% of the ripple voltage. 2) Using a current sense resistor, this measurement relates to PGND minus the voltage of the source on the low-side MOSFET. These values guaranteed by the ILIM Source Current and Current Comparator Offset tests. 3) clks = Switching cycles. 4) Guaranteed by design. See Shoot-Through Delay Timing Diagram on Page 8. 5) Semtech’s SmartDriverTM FET drive first pulls DH high with a pull-up resistance of 10Ω (typ) until LX = 1.5V (typ). At this point, an additional pull-up device is activated, reducing the resistance to 2Ω (typ). This negates the need for an external gate or boost resistor.
