(2) Semtech’s SmartDriver™ FET drive first pulls DH high with a pull-up resistance of 10Ω (typical) until LX = 1.5V (typical). At this point, an additional pull-up device is activated, reducing the resistance to 2Ω (typical). This negates the need for an external gate or boost resistor. 4 © 2006 Semtech Corp. www.semtech.com SC412A POWER MANAGEMENT Electrical Characteristics (continued) |
