Car Power Supply Charging Board

DC~DC Car Charging Board is a DC voltage conversion and power supply module designed for vehicle electronic systems. It converts the DC power supply (such as 12V or 24V) in the vehicle into other required voltages (such as 5V, 9V, 12V, 15V, 20V) to power the digital devices, control systems, communication modules, etc. in the vehicle or connected. This charging board is often used in applications such as vehicle fast charging, power management, and device endurance.

Parameters:

Material:

Circuit board substrate: usually flame-retardant FR-4 glass fiber board or high heat-resistant polyimide material (for high-end automotive grade applications).

Conductive layer: copper foil routing, the thickness is generally 1~2oz to reduce impedance and increase current carrying capacity.

Casing and heat dissipation: Some products are equipped with aluminum alloy heat sinks or metal casings for heat conduction and protection.

Electronic components: integrated voltage regulator IC, inductor, solid-state capacitor, MOS tube, ESD protection device, etc.

FAQ:

Can DC~DC Car Charging Board convert 24V to 5V or 9V?

Yes. This type of module supports converting 12V or 24V input to 5V, 9V, 12V and other output voltages. Some models also support PD fast charging multi-voltage output, which is widely used in different devices.

Will the unstable voltage when the car starts affect the operation of the charging board?

No. Most DC~DC charging boards have a wide input voltage design (such as 8-32V) and overvoltage protection, which can maintain stable output even if the car voltage rises for a short time.

Can it power multiple devices at the same time?

It depends on the product design. If the charging board has multiple output channels or supports higher output current (such as 3A or above), it can power multiple devices at the same time. But it should be noted that the total power load does not exceed the standard.

Does it support fast charging protocols (such as PD, QC)?

Yes. Some DC~DC charging boards integrate USB Type-C control chips, which are compatible with fast charging protocols such as PD3.0, QC3.0/4.0, AFC, etc., and are suitable for fast charging of mobile phones, tablets, and car-mounted devices.

Is the installation complicated? Is it suitable for new energy vehicles?

The installation method is simple, mostly plug-in or screw fixing, supports a variety of electrical interfaces, and is suitable for fuel vehicles and new energy vehicles. You only need to confirm the input voltage and output requirements.
