USB Sort-C Energy Financial institution Reference Design

This reference design is right for varied functions, together with industrial techniques, equipment battery chargers, private electronics, digital nonetheless cameras, and energy banks. 

The USB Sort-C Energy Supply (PD) Downstream Going through Port (DFP) with a cell battery enter represents an development in energy financial institution expertise, providing versatility and effectivity. This configuration permits for high-speed charging of a number of gadgets, supporting varied energy profiles and making certain compatibility throughout a broad vary of devices, from smartphones to laptops. With the flexibility to ship exact energy ranges tailor-made to the gadget’s wants, it maximizes charging effectivity whereas minimizing vitality loss. The mixing of a cell battery enter additional enhances portability and reliability, making it an important device for contemporary, on-the-go existence. Whether or not for private use or in demanding skilled environments, this expertise underscores the way forward for cellular energy options.

The PMP40001 is a reference design by Texas Devices (TI) for a USB Sort-C Energy Supply (PD) Downstream Going through Port (DFP) that’s absolutely outfitted to fulfill fashionable energy administration wants. This design leverages a pure analog configuration for the USB Sort-C supply controller, the TPS25740, simplifying the PD negotiation course of. The design helps three distinct output voltage ranges: 5V, 12V, and 20V, with a most output present of 3A. This enables the design to ship as much as 60W of energy at 20V, making it appropriate for a variety of functions requiring totally different energy profiles. It has excessive effectivity, which might attain as much as 96% at full load. This effectivity is achieved by way of using the high-performance LM5175 buck-boost controller, which not solely enhances the facility effectivity but in addition ensures good thermal efficiency, an important consider sustaining the reliability and longevity of digital gadgets. The design operates inside a large enter voltage vary of 6V to 13.5V, making it suitable with 2S and 3S lithium battery packs, that are generally utilized in moveable electronics and industrial functions.

It will probably help excessive discharge energy as much as 20V/3A, absolutely accommodating the USB Sort-C PD profile 4, which is essential for compatibility with a broad vary of gadgets. Its small measurement and low element depend contribute to its practicality in space-constrained functions, with out compromising efficiency or performance. The pure analog configuration of the USB Sort-C PD negotiation additional simplifies the design, decreasing complexity and potential factors of failure. The design parameters consists of three output voltage choices (5V, 12V, and 20V) with a constant most enter voltage of 13.5V and a minimal enter voltage of 6V throughout all variants. The output present stays regular at 3A for every configuration, leading to output energy capabilities of 15W, 36W, and 60W, respectively. The non-isolated nature of the design, mixed with the buck-boost topology, ensures environment friendly and dependable energy conversion appropriate for DC enter functions.
