Modern power delivery systems with DSPs, FPGAs and CPUs run on lower supply voltages and consume higher current. In fact, sub-1 V voltages are everywhere now. Meanwhile, intermediate bus voltages have ...

1. Typical ISL8117 application that includes external MOSFETs that form a synchronous rectifier output. The ISL8117 from Intersil is a wide input-to-output voltage controller for external synchronous ...

Intersil has announced the Endura ISL6522B single-phase, dual-mode, synchronous-buck PWM controller/driver IC designed to provide soft-start to power sensitive circuits and to handle pre-biased loads.

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 ...

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 ...

Because of the widespread use of pulse-width modulation (PWM), the efficiency of a synchronous buck converter operating in this mode is well understood. However, relatively few designers understand ...

As electronics become more advanced, the need for efficient power management increases. One crucial element of power management is the DC-DC converter, which is a device that converts DC voltage from ...
