Introduction

Recently, ChargerLAB got its hands on a new 100W fast charger from Philips. This charger supports a wide input voltage range of 100–240V AC and features two USB-C ports and one USB-A port. Both USB-C ports support up to 100W output power, while the USB-A port delivers up to 27W. It also supports a 65W + 27W power distribution strategy, meeting fast charging needs for laptops, tablets, smartphones, and more.

During a routine teardown of the Philips charger, it was found to incorporate the RX65T125HS2A, a 650V GaN MOSFET from RUNXIN Micro. Paired with the primary controller chip, this component helps manufacturers deliver a high-efficiency and safe charging experience for users.

This device features low switching losses and is compatible with traditional silicon drivers, eliminating the need for a freewheeling diode, which effectively reduces the overall cost. It can be widely applied in various scenarios, including PD fast charging, communication equipment, automotive applications, and servo motors.

Summary of ChargerLAB

ChargerLAB has learned that the RUNXIN RX65T125HS2A, in line with the current trend of pursuing high efficiency and miniaturization in electronic devices, demonstrates significant application value. From performance and environmental friendliness to packaging, this component meets the design needs of modern GaN fast-charging products. Additionally, the RX65T125HS2A’s compatibility with traditional silicon switch drivers provides an advantage, allowing engineers to upgrade products without making significant changes to existing circuit designs, thereby reducing both R&D costs and time. Its lack of a freewheeling diode further simplifies circuit structures, reduces the number of components, and lowers usage costs, making the product more price-competitive while maintaining performance.
