Did you remember that we have torn down the first Dell 90W GaN charger before? If you haven't seen it, you can click here to view it.

Recently, ChargerLAB got a new model, which is Dell 60W Power Adapter. It adopts ACF topology and integrates two GaN ICS (Navitas NV6115 and Navitas NV6117).

Compared to the 90W model, which still adopts the traditional size, this one is much smaller and easier to use. So, it’s more suitable for people who travel a lot.

Today, we will tear it down to see the internal structure and components.

1. Appearance

Turn to the back, the primary circuit is on the right, and the synchronous rectifier circuit is on the lower-left corner.

The bridge rectifier, SMD Y capacitor, and optocoupler are in the middle.

ChargerLAB found this charger adopts the high-frequency ACF topology, and uses the protocol chip to control the output voltage.

Let's start to analyze the internal components.

OK, that’s all for the Teardown of Dell 60W mini GaN charger. Let’s take a “family portrait.”

Summary of ChargerLAB

The detachable cable design is the most attractive feature, making this charger more like a phone charger than a laptop charger. And you can choose any USB-C cable you'd like.

It adopts the high-performance ACF topology. Its controller comes from Texas Instruments and MPS. 

And the ON Semiconductor driver works with two Navitas GaN ICs (NV6115 and NV6117), which can prove the quality of Navitas GaN IC. The synchronous rectifier comes from Infineon. 

All those components come from well-known brands.
