This super-junction MOSFET enhances the adapter’s reliability and sturdiness by that includes an intensive set of safety options packaged inside a DSO-8 and boasting the 700 V CoolMOS P7’s excessive ESD ruggedness.

Within the more and more stringent panorama of vitality effectivity rules, exterior energy provides are continually scrutinised by regulatory authorities worldwide. Some nations have taken a extra rigorous method, making compliance with these requirements a compulsory requirement, whereas in different areas, adherence stays voluntary. This regulatory surroundings necessitates that energy provide designers stay agile, guaranteeing their merchandise meet and exceed evolving requirements. In response to this demand for larger effectivity and decrease standby energy consumption in a cheap package deal, Infineon Applied sciences has unveiled its fifth-generation Fastened Frequency (FF) controller expertise.

This reference design REF_5GSAG_18W1 by Infineon Applied sciences is particularly tailor-made for an 18 W adapter energy provide to be used with set-top packing containers. The design utilises the ICE5GSAG, the most recent iteration of Infineon’s FF controller, paired with the CoolMOS P7 IPN70R1K2P7S super-junction MOSFET. This mix facilitates an influence provide resolution that’s not solely extremely environment friendly but in addition boasts a low standby energy draw, guaranteeing compliance with even essentially the most demanding worldwide effectivity requirements.

The ability provide design is notable for its common enter characteristic, which permits compatibility throughout a broad spectrum of world electrical requirements, making it a flexible resolution for varied geographic markets. It outputs a secure remoted +12 V/1.5 A by way of a single-layer printed circuit board (PCB), optimised for price and effectivity. The design incorporates a complete suite of safety mechanisms built-in into the controller. These embody safeguards in opposition to enter line overvoltage, VCC over and below voltage, overload/open-loop situations, overtemperature, and present sense short-to-ground incidents, together with a mechanism to restrict the charging present in case of VCC short-to-ground eventualities. Moreover, the 700 V CoolMOS P7 (IPN70R1K2P7S) is provided with an ESD safety diode, enhancing the system’s robustness in opposition to electrostatic discharge and guaranteeing its reliability below harsh situations.

The adapter’s design delivers as much as 18 W of steady energy output throughout a common enter voltage vary. It achieves excessive common effectivity and maintains low standby energy consumption, aligning with the European Union’s Code of Conduct (CoC) Model 5 Tier 2 requirements for single-voltage exterior AC-DC energy provides. Together with a complete safety characteristic set housed inside a DSO-8 package deal and the excessive ESD ruggedness of the 700 V CoolMOS P7, the super-junction MOSFET underscores the adapter’s reliability and sturdiness. Furthermore, an auto-restart safety scheme is included to minimise service interruptions, enhancing the end-user expertise.

The reference design is examined by Infineon Applied sciences, encompassing specs, schematics, a invoice of supplies (BOM), PCB structure, and detailed transformer design and development pointers. This thorough documentation ensures that energy provide designers can quickly develop and deploy options that meet the essential wants of right this moment’s energy-conscious and efficiency-driven market.
