Infineon launches new generation ZVS flyback converter chipset for advanced USB-C PD adapters and chargers

 


【Lansheng Technology News】January 24, 2024. With the increasing popularity of USB-C Power Delivery (PD) charging technology, the demand for highly compatible chargers in the entire consumer market is also increasing. Today, users demand adapters that are both powerful and compact. Infineon Technologies AG introduces the secondary-side controlled ZVS flyback converter chipset EZ-PD™ PAG2 to meet this need. The chipset consists of two different models, EZ-PD PAG2P and EZ-PD PAG2S, integrating USB PD, synchronous rectifier and PWM controller. It ensures efficient communication and isolation between the primary and secondary sides using the pulse-to-edge converter (PET) CYPET121. The product improves efficiency by supporting innovative non-complementary active clamped flyback (NCP-ACF) and zero-voltage switching quasi-resonant flyback (QR-ZVS) topologies for energy-efficient USB-C adapters, Charger and travel adapter.


The EZ-PD PAG2 series chipset provides a versatile, efficient power delivery solution for a variety of applications. The chipset supports PD 3.1 standard power range (SPR) with programmable power supply (PPS) as well as extended power range (EPR) of 28V for fast and reliable charging. At the same time, the chipset is suitable for various powers, is compatible with charging protocols such as BC v1.2, AFC, Apple charging and QC5.0, and supports universal AC line input from 90 VAC to 265 VAC, improving the global popularity of this semiconductor device. availability.

Infineon‘s product implements programmable soft-start using an external SS capacitor, with controlled power-up, Discontinuous Conduction Mode (DCM), Critical Conduction Mode (CrCM) and Continuous Conduction Mode (CCM) as well as bursts for different load conditions. hair and jump modes. This adaptability makes it ideal for charging equipment and devices in different regions. The features of the EZ-PD PAG2 series chipset ensure efficient and flexible power management to meet various needs.


The EZ-PD PAG2 series chipsets include four dedicated products:

The secondary side ACF controller EZ-PD PAG2S-AC has efficient energy recovery and USB-PD protocol functions.


Another ZVS controller, EZ-PD PAG2S-QZ, mainly adopts QR-ZVS flyback architecture and has USB-PD protocol function.


The primary-side high-voltage startup controller EZ-PD PAG2P integrates various functions that improve system performance, including high-voltage startup, PET receiver, gate driver and fault protection. The EZ-PD PAG2P also features an x-capacitor discharge function and a Vcc boost converter.


The USB PD controller EZ-PD PAG2S-PS with integrated synchronous rectification (SR) can be paired with third-party pulse width modulation (PWM) controllers. It features a shunt regulator that enables constant voltage and constant current control via an optocoupler. This controller has best-in-class SR performance and fast turn-on/off times, and supports volt-second integration to prevent false SR turn-on.

What are the Benefits of Power Optimizers?

Image
  Power optimizer for solar panels is a DC/DC converter that is connected to each solar panel in the PV system, turning them into smart modules. By constantly monitoring the maximum production capacity of each individual solar module, optimizers can increase your PV plant energy production – potentially increasing revenue and shortening system payback time. Simply put, the main benefit of power optimizer is that it maximizes the performance of each panel individually. What are the benefits of power optimizers and why are they needed? When installing solar panels, the panels are connected into groups or arrays. In the case of roof-mounted and in-roof panels, there are usually 12-20 solar panels in one group. If the productivity of one of these panels decreases (shadows from trees and clouds, dust, bird droppings, failures of PV components and other factors), then the productivity of the whole group decreases. Defective or shaded panels may produce 15 to 25 percent less solar energy ...

What is a Power Conditioner?

Image
  Looking to protect your sensitive and expensive electronics? Surge protection is a great start, but power conditioners also offer valuable protection for components in entertainment and sound systems, as well as home office devices. What does a power conditioner do that a surge protector can’t? Surge protectors are a great defense against damaging voltage spikes. However more than surges and spikes can effect certain sensitive electronic devices. Radio frequency interference (RFI), electro-magnetic interference (EMI) and voltage fluctuations can also effect sound, entertainment, and office devices, causing a reduction in sound and picture quality. How does it work? Power conditioners act as a buffer between the outlet and your system, smoothing out voltage fluctuations as well as radio and electromagnetic interference that can effect system performance. Initially used in industrial, research and laboratory applications, not long after the introduction of home computer systems, th...
