Innovative zero voltageswitchThe chipset achieves a 100W + power level PSU with the lowest BOM cost, and the size is reduced by 50%.

China Beijing, July 5, 2021 - LeadingbatterywithPower management,Wi-fiLow power consumptionBluetooth(Ble), industrial edge computing solution supplierDialogSemiconductor (German stock exchange transaction code: DLG) today announced that the introduction of innovative numeric zero voltage switch (ZVS) chipset, power supply (PSU), high power density (HPD), dimension than traditional high power PSU Reduce 30% to 50%.

Dialog easy to use ZVS RApiDCHARGETM solutions include primary side controllers IW9801 and secondary side IW709 USB PD protocol IC. The secondary side digital compensation loop ensures stability and eliminates the need for additional compensation components. The secondary side IW709 integrates a synchronous rectifier controller, further reduces the number of overall components.

The solution provides seamless multi-mode control, achieving up to 94% efficiency, eliminating the audible noise in high-power charging, realizing a charger with a small shape and a safe fever, is a standby power consumption below 20mW solution. The chipset provides powerful overvoltage protection (OVP), overcurrent protection (OCP), users can configure over-temperature protection, common protection, input power / undervoltage protection, vsense / isenseShort circuitProtection, output short circuit protection and other functions, as well as additional primary side overcurrent protection and overvoltage protection.

DAVIN LEE, senior Vice President and Advanced Mixed Signal Business Unit, said: "Dialog has been established on the basis of our profound AC / DC technical expertise, and further expands our target market. High power density PSU market. The innovative ZVS chipset helps customers easily design not only small size, but also very cost-effective higher power density charger. "

Dialog's ZVS chipset supports most fast charge protocols, including USB PD 3.0 and other third-party proprietary protocols that support programmable power (PPS) protocols. The chipset uses a maximum of 200kHz switching frequency, making the design engineer to use smaller and lightertransformerAnd smaller passive devices, thereby reducing the size and weight of the charger. This complete solution adopts built-in digital compensation, makingCircuitDesign is more easier than the simulation scheme.
