Parity Generation on the TMS320C54x
Texas InstrumentsIn many applications simple parity checks are often introduced to provide some minimal error detection capabilities when the transmission channels are less than perfect. The 8-bit data bus in personal computers is protected with the addition of a ninth parity bit. Serial asynchronous data communications frequently embed an extra parity bit in the data which is to be transmitted. Several of the di
TVP5150AM1 Powerdown Mode
Texas InstrumentsMobile applications such as cell phones and PDAs have low power consumption as a key requirement. The TVP5150AM1 offers very low power consumption in normal operation. When the TVP5150AM1 is not in use the power consumption must also be very low. This application report outlines how to correctly implement the powerdown mode to ensure the lowest power consumption.
U-150 Applying the UCC3570 Voltage-Mode PWM Controller to Both Off-Line
Texas InstrumentsThe UCC3570 families of pulse-width modulators are for application in isolated switching supplies using primary-side control and a voltage-mode feedback loop. BiCMOS processing provides higher switching frequencies at lower quiescent current drain while including innovations in both performance and protection features. Its versatility is demonstrated with the description of a 50W wide input-volt
