The conventional boost-converter topology has the potential trap of no short-circuit protection (Fig. 1). Typically, a converter is safeguarded by placing an electronic fuse in front of it. This ...

1. Shown is an example of a simple circuit (TI reference design PMP9759) that bidirectionally drives current through a TEC; the single-chip buck-boost converter requires a minimum number of ...

With a low voltage input (3.3V) being converted to 5 volts, the boost converter with PFET consistently provides 8% higher efficiency over the boost/LDO combo shown in Figure 1. With the circuits under ...

Figure 3 shows a modifiedversion of the circuit with both positiveand negative boost voltages added. Figure 3 A modified version of the circuit has both positive and negative boost voltages added. A ...
