Since their introduction in the mid 1980?s the bipolar UC3842 family of Pulse width modulation (PWM)controllers has grown to become the most widely-used control strategy in the power supply industry. [1] The reasons for success are quite clear the devices feature an elegantly simple yet very effective control architecture they use only 8 pins they can drive MOSFET gates directly and they offer

Texas Instruments and DLP Design, Inc. have released an updated design for the TRF7970A NFC/RFID BoosterPack? plug-in module ? the DLP-7970ABP. This updated design includes new feature additions to su

This application report discusses a solution to the additional power required in those PoE applications that exceed the power requirements defined in the current IEEE802.3af standard. Specifically the document offers a two-pairs solution for 16-W to 18-W powered devices.

This wiki article describes how to set the SDRC registers in the OMAP35x SDRC module depending o

The new 4 to 1 video multiplexer MPC100 opens the door to high-speed signal distribution without the headaches. This component contains four wideband open-loop amplifiers connected together internally at the output with a bandwidth of 180MHz at 1.4Vp-p signal swing. When the user selects one channel by applying a digital 1 to the corresponding SEL input the component acts as a buffer amplifier

This document discusses how a designer can reduce electromagnetic interference (EMI) in digital motor control applications using the Texas Instruments (TI)(tm) TMS320C24x digital signal processor (DSP) controller.This document contains a printed circuit board (PCB) layout of the TMS320C24x with reduced electromagnetic interference (EMI) and includes techniques for implementing code on the TMS3

The OPA128 ultra-low bias current operational amplifier achieves its 75fA maximum bias current without compromise. Using standard design techniques serious performance trade-offs were required which sacrificed overall amplifier performance in order to reach femtoamp (fA = 10^-15A) bias currents.

Brushless DC (BLDC) motors are electronically commutated motors that offer many advantages over brushed DC motors and therefore are becoming very popular industrially and commercially. This application report discusses a sensored 3-phase BLDC motor control solution using MSP430™ as the motor controller. Hall sensors are used to detect the rotor position and close the commutation loop. Both open

DN024 -- 868 MHz, 915 MHz and 955 MHz Monopole PCB Antenna

The LM3647 demo board allows you to create a battery charging solution with little effort.

This reference design is presented to help application designers and others who are trying to use the MSP430 in a system with an input voltage in the range of 3.6 V to 5.5 V and who are also intereste

A common method to improve the stability and bandwidth of a power supply is to use a feedforward capacitor, which is a capacitor placed across the high-side feedback resistor. This capacitor adds a ze

This document discusses how to initialize the TMS320C3x to interface with the TLC320AD58C 18-bit stereo analog-to-digital converter (ADC) without glue logic.The TLC320AD58C serial interface provides several master and slave modes for 16-bit or 18-bit data output to be compatible with a wide range of DSPs. To interface with the TMS320C3x 32-bit floating-point DSP the 18-bit master mode '100'
