Output Voltage Detector from Diodes Incorporated Improves Transient Performance of Primary-Side Regulation Systems

Diodes Incorporated (Nasdaq: DIOD), a leading global manufacturer and supplier of high-quality application specific standard products within the broad discrete, logic and analog semiconductor markets, today introduced the AP4341S. This device offers a high-performance and cost-effective solution for power adapters and chargers used in portable and consumer applications. This output voltage detector uses a patented design to address the need for fast transient performance in primary-side regulation systems.

The AP4341S works in conjunction with primary-side regulation controllers, such as Diodes’ AP3776 or AP3785 devices, to monitor the secondary-side voltage and provide a periodic ‘wake-up’ signal to the controller, coupled via the transformer, when that voltage drops below a certain threshold. Fast detection, with a pulse at 33kHz, delivers improved transient performance and greater efficiency, supporting green-mode applications through reduced standby power losses.

Offered in a SOT23 package and requiring no external components, the AP4341S provides a highly cost-effective PSR solution. Further information is available at www.diodes.com.
