Synchronous Rectifiers of a Current Doubler
Texas InstrumentsDriving a current doubler synchronous rectification output stage can be a very complex task especially for a phase shifted full bridge topology. However using the A and B outputs of the UCC3895 along with the UCC37324 dual 4-A MOSFET driver direct PWM control of a synchronous rectifier current doubler output stage achieves. This technique provides the proper gating and timing signals necessary

Not All Jitter Is Created Equal (Rev. A)
Texas InstrumentsThis application report offers a tutorial discussion on jitter in switching DC-DC converters. Not all power supply designs are equally susceptible to jitter nor are they equally affected by jitter. Modes of switching jitter are defined and explained for several popular control architectures which are then analyzed for sources of jitter. An example contrasting the amount of jitter and effect on o

Using the CSL to complement OS dispatcher in handling Cascaded Interrupts
Texas InstrumentsThis application report discusses how CSL's INTC module could be used to share the task of dispatching interrupts with the OS in scenarios where the OS's interrupt dispatcher does not comprehend cascaded interrupts.
The solution involves having the CSL dispatch the cascaded interrupts alone while completely leaving the job of dispatching primary CPU interrupts to the OS.
