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 synchronous buck-boost converter IC from Linear Technology builds on the success of the company’s LTC3440 by extending that device’s input voltage range and by making burst-mode operation ...

Several power supply topologies, including SEPIC and flyback converters [1], generate a non-isolated, positive DC voltage from a positive DC input voltage range that extends both above and below the ...

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 ...

Buck converters are a critical element in modern power management, providing efficient voltage step‐down in a wide range of systems from battery-operated devices to industrial applications. Their ...

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 ...

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 ...

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 ...
