Designing Overcurrent protection for TPL7407L Peripheral Driver
Texas InstrumentsMicrocontroller units (MCUs) are generally limited with lower drive on the I/Os. Most of the applicationsrequiring MCU boards to drive high-current loads need discrete implementation and additional components which use a lot of board space. This board space is called a peripheral driver section. The TPL7407L device is an integrated peripheral driver with seven channel drivers inside. The TPL740

Using TPS54x80 Tracking SWIFT(TM) dc/dc Converters f/Simult. Tkg of Input Supply
Texas InstrumentsHigh-performance signal processing devices such as FPGAs and DSPs require multiple power supply voltages for operation. The order and timing in which these supply outputs power up and down is usually specified. A design example using the TPS54380 is shown for the case where the power supply to be tracked is also the input voltage to the TPS54380. Information is provided for adjusting the start-u

D-CAP(TM) Mode With All-Ceramic Output Capacitor Application
Texas InstrumentsThe TI D-CAP™ Mode controller is widely used in computing power management. D-CAP™ Mode requires an appropriate amount of equivalent series resistance (ESR) on output capacitors to ensure the loop stability. However many customers prefer to use a low-ESR capacitor such as a ceramic output capacitor. Sufficient output ripple however may not be available in this case to ensure the system stabili
