TPS25810 Charging Port Over USB Type-C
Texas InstrumentsThe TPS25810 is a USB Type-C downstream facing port (DFP) controller that monitors the USB Type-C configuration channel (CC) lines to determine when a USB device is attached. When the upstream facing port (UFP) device Type C-to-B dongle is plugged in, the port supports connection of Type-B receptacle devices such as a mouse, smartphones, keyboards, external hard drives, and so forth. As these devices monitor the USB 2 data line (D+/D–), the TPS2544 USB charging port controller can be added to provide the electrical signatures on D+/D– to support BC1.2 and non-BC1.2 compliant charging schemes. This application note presents the design solution which offers fast charging of popular mobile phones, tablets, and media devices over the USB Type-C port.

Five Steps to a Good PCB Layout of the Boost Converter
Texas InstrumentsA good PCB layout is critical for the boost converter. The reason is that the boost converter is sensitive to parasitic capacitance and inductance because of the switch-mode operation. The bad PCB layout would introduce large parasitic capacitance and inductance, which would cause high output ripple, poor output voltage regulation and current limit accuracy, electromagnetic interference (EMI) problem, and even failure by the high voltage spike. Proper PCB layout will help to avoid most of these problems of the boost converter without extra cost if thought is spent before the first PCB is built.
Copying the layout of the boost converter from its datasheet or evaluation module (EVM) is easiest, but the layout may not fit the system board. So this application note details five steps that help to design a good PCB layout for the TPS61xxx converter.
