Share a PD fast charging power deception chip CH224 is very practical [Copy link]

 

Chip function: induce PD charger to output maximum power, support maximum induced voltage of 20V. Supported protocols: mainstream fast charging protocols such as PD/QC
Chip package: ESSOP10
Chip application: wireless charging input, 10W/15W wireless charging, both require input power greater than 15W, the mainstream solution is to directly use 9V/2A or 12V1.5A DC power supply, a small amount is also induced by QC and other protocols, and PD induced is more convenient. For

lithium battery equipment such as power tools, use PD chargers to increase the power receiving capacity of the powered equipment with high power and greatly reduce the charging time.
Interface conversion cables can upgrade the power supply of laptops to PD power supply (small size, easy to carry, only need to bring a charger when traveling), the general laptop power supply is about 20V3A, which can be induced by this chip.
PD power receiving circuit:

Although this is an advertisement, as a new product, it is good to enrich everyone's design.

It is a chip that can trick the PD charger into outputting high power. Generally, the PD charger outputs 5V by default when there is no protocol handshake. When the receiving end has a protocol that can handshake with the PD charger, the charger can be tricked into outputting a maximum power of 20V 5A. Of course, the output of 20V 5A also requires the charger's own power support and wire support. Most of the PD chargers currently on sale are multi-protocol, such as supporting PD/QC/AFC/FCP/SCP/APPLE2.4/BC1.2, etc. This power receiving chip can greatly improve the charging efficiency of the receiving device and save charging time, similar to mobile phone fast charging.

The most direct impact is that future designs of Bluetooth speakers, power tools and other products will be able to be charged for 5 minutes and used for 2 hours.

Which manufacturer is this from? Is it Qinheng?

I just missed the picture below. It is indeed from Qinheng. I wonder if I can get a single board to play with.

Can this chip realize the step voltage regulation in the PD protocol?

Bro, where can I buy this verification board?
