A four-switch buck-boost converter benefits from synchronous rectification ... The forward-voltage drop of a typical Schottky diode is around 0.6 V, and the diode conduction loss could be significant ...

Figure 3 presents a circuit with an LT8350S buck-boost switching regulator. This device can carry up to 6-A switch current and has an input voltage range of 3 to 40 V. To reduce the generated EMI ...

A buck-boost switching controller IC can accept a wide range of input voltages that are above, below, or equal to the output voltage and still provide a constant regulated output to the load.

The buck-boost converter uses a four-switch configuration, operating as a buck ... Below 3.5V, the buck-boost converter input current increases (Figure 6). This increasing current, compounded with the ...

Its internal 4-switch buck-boost controller operates from input voltages above ... of continuous LED power with efficiencies up to 98.5%. LED current accuracy of ±6% ensures constant lighting while ±2 ...

Its internal 4-switch buck-boost controller, combined with four external N-channel MOSFETs, can deliver from 10W to over 100W of LED power. Its buck-boost capability makes it well suited for ...
