Low-dropout regulator, SMPS cascade suppress ripple, maintain efficiency
11.25.2017 · Circuits
A step-down SMPS efficiently converts unregulated power to a regulated output voltage. However, unwanted switching-induced ripple and input transients may appear on the output. Applying noisy power to an RF power amplifier can inject spurious signals or modulated noise into the broadcast spectrum...
Three-Phase Half-Bridge Gate Driver from Diodes Incorporated Simplifies BLDC and PMSM Motor Drive
