    PDF, 356 Kb, Revision: C, File published: Apr 23, 2013
    The LM3478 is a low side N-Channel controller for switching regulators. Like many switching controllers,the added flexibility in component selection can cause problems for users when determining thecompensation scheme. It is the goal of this application report to present a decent groundwork to allow thereader to select with confidence the correct compensation components. To achieve this we l

    PDF, 220 Kb, Revision: E, File published: Apr 23, 2013
    In a single ended primary inductance converter (SEPIC) design, the output voltage can be higher or lowerthan the input voltage. The SEPIC converter shown in Figure 1 uses two inductors: L1 and L2. The twoinductors can be wound on the same core since the same voltages are applied to them throughout theswitching cycle.
