Evaluation of Nickel/Palladium/Gold-Finished Surface-Mount Integrated Circuits
Texas InstrumentsTexas Instruments has introduced a refined version of its nickel/palladium (NiPd) finish for integrated circuit (IC) package leads. The enhanced version of lead finish is nickel/palladium/gold (NiPdAu). TI has a long and successful history with the NiPd finish. There are more than 40-billion devices in the field with TI NiPd-finished leads. TI introduced the NiPd finish in 1989 and many papers a

Highly Integrated PMIC for Powering the SiRFatlasIV(TM)
Texas InstrumentsThis design was created to help those needing to power the SiRFatlasIV and doing so by implementing a highly integrated and efficient design using the TPS65072 power management unit.
Live Insertion
Texas InstrumentsMany applications require the ability to exchange modules in electronic systems without removing the supply voltage from the module (live insertion). For example an electronic telephone exchange must always remain operational even during module maintenance and repair. To avoid damaging components additional circuitry modifications are necessary. This document describes in detail the phenomena tha

Reducing Ringing Through PCB Layout Techniques
Texas InstrumentsDesigners must consider several topics when designing a printed-circuit board layout for a dc-to-dc converter. In particular the layout of the Power Stage components within a nonisolated synchronous buck converter requires special attention in order to optimize the overall performance of the switching function. The Power Stage in this application report is defined to include the input capacito
Interfacing the DAC8831EVM to TMS320C5x Processors

U-144 UCC3806 BiCMOS Current Mode Control IC
Texas InstrumentsThe UCC3806 BiCMOS current-mode controller has the advantages of reductions in current consumption in power loss and in propagation delays within the IC. The UCC3806 is pin-for-pin compatible with the popular UC3846 and UC3856 controllers. With minimal part changes this device may be suitable for retrofit into many existing designs where higher power consumption and propagation delays posed pro
How to reduce current spikes at AC zero-crossing for totem-pole PFC
Texas InstrumentsPower factor correction (PFC) is widely used in AC/DC power supplies with an input power of 75 watts or greater. PFC forces the input current to follow the input voltage so that any electrical load appears like a resistor. Amongst all the different PFC topologies, the totem-pole PFC has recently received more attention because it uses the least number of components, has the smallest conduction loss, and has the highest efficiency. Typically, a totem-pole PFC cannot operate in continuous-conduction mode (CCM) because of the slow reverse recovery of the MOSFET’s body diodes. However, with the advent of the galliumnitride (GaN) FET, its diode-free structure makes the CCM totem-pole PFC possible.

Practical Technique for Minimizing the Number of Measurements in Sensor Signal
Texas InstrumentsThe output of many modern bridge type sensors contains errors that must be eliminated through calibration. One major source of error is variation of sensor span and offset from device to device and their respective drifts with temperature. These drifts can be non-linear. Another source of error is the nonlinearity of the sensor output with applied stimulus. Signal conditioning electronics can also
