PWM-locked-loop seems to work this time (in LTspice, at least)

I have had an on-going mission to design a universal-ish pcb that will convert a PWM waveform at one frequency into to another frequency while retaining the mark-space ratio. The obvious answer is a ...

Circuit VR: An (Almost) Practical Buck Converter

In the last installment of Circuit VR, we walked around a simplified buck converter. The main simplification was using a constant PWM signal. The result is that the output voltage is a fixed fraction ...

A New Trilogy of LTSpice Circuits with NTC Thermistors, Part I: LED Current Dimming with LT3474 and NTC Thermistor Temperature Control

Earlier this year, we presented a series of LTSpice simulations with temperature control provided by NTC thermistor SPICE models driven by a voltage: Old-School Analog Temperature Control Circuits ...

A New Trilogy of LTSpice Circuits With NTC Thermistors, PART III: A Last Burst of LTSpice Simulations for Temperature Control Circuits (LTC1040, LT8391 and more)

We are going to end our latest trilogy of LTSpice simulations with another demonstration of the powerful computing capabilities of this SPICE software in the field of NTC thermistor temperature ...
