Introduction

Although the Mercedes-Benz V-Class original 36W charger looks like a general car charger, it is not essentially a car charger because it is a part of the car itself, which connects to the power by its metal plug instead of a cigarette lighter.

ChargerLAB has gotten it, and we will take it apart.

Appearance

The charger consists of three parts: the charger body, the wire and the connector.

The small rectangular board has a buck protocol chip for USB-A port output, and the back of the small round board has the inductor and solid capacitor.

The input filter solid capacitor is from Yunxing Electronic, with a specification of 100μF 35V and protective plastic insulation.

The USB-A port buck protocol IC adopts iSmartWare SW3521, a highly integrated fast charging protocol charging chip that integrates a 3.5A high efficiency synchronous buck converter and supports multiple fast charging protocols such as QC/AFC/FCP/SCP/PE/SFCP and CC/CV modes. It only needs a few peripheral components to form a complete high-performance fast charging protocol charging solution.

After taking the charger apart, ChargerLAB found that the iSmartWare SW3521 is also adopted by the Baseus 160W multi-port fast charging car charger.

The buck inductor is covered by a heat shrink tube for insulation.

The USB-C port buck protocol IC adopts iSmartWare SW3522, a highly integrated fast charging protocol charging chip that integrates a 3.5A high efficiency synchronous buck converter and supports multiple fast charging protocols such as PD/QC/AFC/FCP/SFCP and CC/CV modes. It only needs a few peripheral components to form a complete high-performance fast charging protocol charging solution.

After taking the charger apart, ChargerLAB found that the iSmartWare SW3522 is also adopted by the Baseus 160W multi-port fast charging car charger, JOYROOM 45W 3-in-1 car charger, and so on. The other fast charging chips of iSmartWare are also adopted by Asus, Nubia, Rapoo, UGREEN, Lenovo and dozens of other products of well-known brands.

OK, that's all for the teardown of the Mercedes-Benz V-Class original 36W charger. 

Summary of ChargerLAB

The Mercedes-Benz V-Class original 36W charger is equipped with one orange USB-A port and one black USB-C port, supporting QC2.0/3.0, AFC, FCP, SCP, PE2.0, PD3.0 and PPS fast charging protocols, with a maximum power of 36W.

After taking the charger apart, ChargerLAB found that the charger adopts the iSmartWare SW3521 and SW3522, two buck protocol ICs to control the USB-A and USB-C ports output, respectively, with excellent compatibility. In addition, the high integration also helps the charger to be tiny.
