Preface
As the wheels of history roll forward, innovation in the field of power devices has never stopped. In order to improve the power density and conversion efficiency of power supplies, major packaging and testing manufacturers continue to explore new power device packaging processes and packaging forms. At present, MOS tubes have gradually shifted from the early use of TO lead packages to surface mount types such as TOLL, QFN, SOP, STP, etc.
The full English name of TOLL package is Transistor Outline Leadless, as the name suggests, it is a leadless power device. Compared with the common D²PAK (TO263) package, the package shape is smaller and more suitable for PCB boards, and has the characteristics of low package resistance, low parasitic inductance, low thermal resistance, low voltage overshoot, and high current, and has been widely used in outdoor power supplies, inverters, electric bicycle chargers, BMS systems and other equipment.
The application of TOLL package MOS in outdoor power supply
When sorting out the previous dismantling cases, the charging head network found that a variety of outdoor power supply products are equipped with TOLL encapsulated MOS tubes. Some of the parameters of several devices that appear in the article are shown in the figure, and the following editor will introduce them to you in detail.

Summary of the charging head network
Throughout the history of outdoor power extraction, it can be found that the basic path is from the initial reliance on petroleum generators to the later lead-acid battery with inverter system, and the two technological breakthroughs are bringing convenience to outdoor electricity consumption. However, the real revolutionary change occurred in recent years with the advent of outdoor power supply, and now the new outdoor power station has completely changed the experience of outdoor electricity consumption for consumers with its characteristics of miniaturization, low noise and high efficiency.
For the power devices that form the core part of the outdoor power supply, its development history also follows the same trend. The introduction of TOLL packaging technology enables power devices to be surface-mounted, which has significantly improved efficiency, greatly reduced losses, and significantly reduced volume, making outdoor energy storage power supply a step further on the road of pursuing lightweight, and providing a more convenient and efficient power solution for people who often run outdoors.
