Relentless improvement continues in small switching buck regulators. Allied Component Works recently worked on a customer application requiring a typical 5V to 3.3V step down regulator.  The application might have supported a modular solution except for certain required power sequencing features.  With that we had an opportunity to work with a newer series of switching regulators (TLV62130) from Texas

Discrete switched capacitor filters still offer a viable and flexible option for signal processing. Allied Component Works recently worked on a customer application requiring a discrete active filter for a control system’s analog input signals in a subaudio frequency range.  An eight pole butterworth filter was needed, and needed fast, to stabilize the customer’s control
