When the SS voltage reaches 2.0V, the secondary loop including the 3% window comparator is en- abled. Lastly, the SS voltage is clamped at 2.4V, ending the soft start charge cycle. Hiccup Mode When ...

Zero Crossing Detection In some applications, it may be undesirable to have negative conduction current in the inductor. This situation happens when the ripple current in the inductor is higher than the load current. Therefore, the SP6120 provides an option ...

The NFET/PFET programmability is for the high side MOSFET. When designing DC/DC converters not always obvious when to use an NFET with a charge pump or a simple PFET for the high side MOSFET. Often, the controller has ...

It is during this interval that the 3% window comparator has taken control away from the main loop. The main loop regains control only if the output voltage crosses through its regulated value. Also notice where the 3% comparator ...

Inductor Selection There are many factors to consider in selecting the inductor including cost, efficiency, size and EMI typical SP6120 circuit, the inductor is chosen primarily for value, saturation current and DC resistance. Increasing the inductor value will ...

SP6120 adjusts the inductor current to the new value. Therefore the capacitance must be large enough so that the output voltage is held up while the inductor current ramps up or down to the value corresponding to the new load ...

Layout Guideline PCB layout plays a critical role in proper func- tion of the converters and EMI control. In switch mode power supplies, loops carrying high di/dt give rise to EMI and ground bounces. The goal of layout optimization is ...
