Figure 1: Lithium-Ion to 3.3V 1.3MHz Step-Down Buck Converter. Figure 2: Lithium-Ion to 3.3V 1.5MHz Buck-Boost Converter (Buck: Q1 and Q2 Switching, Q4 On; Boost: Q3 and Q4 Switching, Q1 On) ...

He built a buck converter and made measurements about its efficiency using different configurations. The test setup is simple. He monitors the drive PWM with a scope and has power meters on the ...

Figure 1 shows a conventional two-switch buck-boost converter. The power stage consists of two switches (Q 1 and Q 2), two diodes (D 1 and D 2), a single inductor (L 1), and input and output ...

The synchronous buck converter in Fig. 1 is the most popular topology in the PC market. ... L1 and L3 are loops that are barely long enough to accommodate the scope current probe, ...

Buck-Boost Converter: A type of DC-DC converter capable of both stepping down (buck) and stepping up (boost) the input voltage while maintaining the same polarity.

[Hugatry] wanted to replace the adjustment pot on an LM2596 buck converter with a microprocessor-controlled voltage. The regulator IC uses a divider to generate a 1.25V reference from the output. T… ...
