Efficiency should be a major consideration when designing a flyback switching power supply. It can impact many aspects of a product design from enclosure size and ventilation to safety qualification.

The HiperTFS-2 devices incorporate a high-power two-switch-forward converter and a mid-power flyback (standby) converter into a single, low-profile eSIP power package. The single chip solution ...

Cable and xDSL modems are experiencing increasing popularity. For this reason, many designs are now required to interface with existing telephones at the subscriber's location. The subscriber line ...

While switch-mode power supplies operate at frequencies well above the range of human hearing, they can produce audible noise under certain load conditions. Potential sources of audible noise can vary ...

Power Integrations has announced the fifth generation of its InnoSwitch isolated fly-back ac-dc converter ICs, which removes the need for primary-side active clamping when operated in zero-voltage ...

The most common type of power supply today is the switching supply. These units use pulse-width modulation (PWM) to regulate output. Supplies today employ several different PWM circuit configurations.

Synchronous rectification is adopted to reduce conduction losses at heavy load, using TEA1791/1761 as a flyback switching power supply or replacing Shottky-barrier diodes with TEA1791A/1795 linear ...

On paper, electricity behaves in easy-to-understand, predictable ways. That’s mostly because the wires on the page have zero resistance and the switching times are actually zero, whereas in real life ...
