bq20z70/90 Printed-Circuit Board Layout Guide

With the introduction of commercially available amplifiers using the current feedback topology byComlinear Corporation in the early 1980’s previously unattainable gain and bandwidths in a DC coupledamplifier became easily available to any design engineer. The basic achievement realized by the currentfeedback topology is to de-couple the signal gain from the loop gain part of the overall tra

The UC3825 family of PWM control ICs is optimized for high-frequency switched-mode power-supply applications. This application note describes the development of a 1.5 MHz current-mode IC-controlled 50W power supply. Push-pull topology is used for this DC-to-DC converter application of +48V input to +5V at 10A output. Increases in switching speed and dynamic performance are made possible by the U

Power factor correction (PFC) is used in power systems operating from single phase AC to correct for thenon linearity of the rectifier. Use of PFC in motor drives is increasing because of increased regulation fromthe power utility side. However integration of PFC and field oriented control of motor on a single controllerremains challenging from a processor bandwidth point of view while keep

Especially for switch-mode power supplies (SMPSs), the printed circuit board (PCB) layout is a critical but often under appreciated step in achieving proper performance and reliability. Errors in the PCB layout cause a variety of misbehaviors including poor output voltage regulation, switching jitter, and even device failure. Issues like these should be avoided at all costs, since fixing them usually requires a PCB design modification. However, these pitfalls are easily circumvented if time and thought are spent during the PCB layout process before the first PCBs are ever ordered.

This article presents five simple steps to ensure that your next step-down converter’s PCB layout is robust and ready for prototyping.

This application report provides the basic operating theory and key design considerations for the bq27500 and bq27501 single-cell Li-ion fuel gauge ICs with the Impedance Track™ algorithm. The bq27500/501 ICs are designed to reside on the system's main board in applications with an embedded or removable battery pack. To achieve best results the fuel gauge ICs must work properly with the ba

This application report contains implementation instructions for the DDR2 interface contained on the TMS320DM357 digital media system-on-chip (DMSoC) devices. The approach that was taken to specify interface timing for the DDR2 interface is quite different than on previous devices.

The previous approach specified device timing in terms of data sheet specifications and simulation models. The sy

The UCD3138 is a digital power supply controller from Texas Instruments offering superior levels of integration and performance in a single chip solution. The flexible nature of the UCD3138 makes it suitable for a wide variety of power conversion applications. In addition multiple peripherals inside the device have been specifically optimized to enhance the performance of AC/DC applications such

This application note proposes a novel approach--using adapters--to running xDAIS algorithms with a Codec Engine (CE) application. An adapter fits between the Codec Engine Runtime and the algorithm (usually on the DSP). Its purpose is to adapt the interface exposed by the algorithm so that it better conforms to a given system programming interface (SPI) such as xDM. In addition an adapter can be
