In the last installment of Circuit VR, we walked around a simplified buck converter. The main simplification was using a constant PWM signal. The result is that the output voltage is a fixed fraction ...

This application note covers the steps required in choosing the inductor and to calculate the value used in buck regulator IC circuits. Switching regulators are used in a variety of applications to ...

A high-efficiency, single-channel, synchronous-buck converter IC intended for point-of-load (POL) applications employs on-chip MOSFETs and proprietary mode control with adaptive on-time architecture.

PCB layout design for switching power supply IC is as important as the circuit design. Appropriate layout can avoid various problems caused by power supply circuit. Major problems that arise from ...

1. A simplified application circuit ties eight PGND, six PVIN, and seven SW pins together. Figure 2 shows the internal construction of the TSP548D22’s LQFN-CLIP (RVF) package. Called “Powerstack,” it ...

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 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 ...

Another lifetime ago, and as a young engineer, I had to design a power conversion system. The input power came as raw electrical energy from a jet engine during flight. The output power was input to ...

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 ...
