Even switch-mode power supplies with a fixed switching frequency do not always show a continuing pattern of pulses. In some conditions, pulses are omitted for various reasons. This is important to consider for output ripple voltage and EMI effects. ...

Applications for using a single pushbutton to advance a circuit to its next logical state are legion. Typically, there are just “on” and “off” states, but there can be more. The heart of the circuit is a toggle flip-flop ...

Abstract There is a new product type in the industry, the digital low dropout (LDO) linear regulator. It offers telemetry and adjustability of a linear power supply in a very small footprint. Such solutions are used in ultralow noise applications ...

This article will illustrate how special converters equipped with PassThru mode can be useful when the circuit’s input voltage is too high or too low to power a load. It will give examples of how PassThru mode is used with buck-boost ...
