The most common switching-power topology is a buck converter, which efficiently transforms high voltages to low voltages. Figure 1 shows a typical buck converter in which the N-channel MOSFET, Q 1, ...

This application note explains the calculation of external capacitor value for buck converter IC circuit. Change of capacitance value due to temperature can obtain stable temperature characteristic by ...

Texas Instruments’ TPS53915 (Fig. 1), can supply up to 12 A output that is adjustable from 0.6 V to 5.5 V. Its input voltage ranges from 1.5 V to 18 V. A 4.5 V to 25 V VDD input powers an internal 5 V ...

Buck converters, a pivotal class of DC–DC converters, are widely implemented in modern power electronics to achieve efficient voltage step-down conversion. Recent advancements focus on enhancing ...

The IR3621M and IR3621F from International Rectifier are voltage-mode, dual-output bi-phase synchronous buck controller-driver ICs for high performance point-of-load (POL) buck converters used in ...

STMicroelectronics has created a 5W dc-dc buck converter IC that produces a regulated non-isolated output plus one or more transformer-coupled isolated outputs. The isolated secondary voltage is ...

The SPI-8010A is a high-efficiency (94%), adjustable-output, 3-A buck converter IC, available in an HSOP16 package with enhanced thermal-dissipation capability. The package's special ground-potential ...

DC to DC conversion has come a long way. What was once took an electromechanical vibrator and transformer has been reduced to a PC board the size of a largish postage stamp that can be had for a ...

Designing a circuit is a lot easier on paper, where components have well-defined values, or lacking that, at least well-defined tolerances. Unfortunately, even keeping percentage tolerances in mind ...
