  • Design Considerations and Dynamic Technique for Digitally Controlled Variable Frequency DC-DC Converter
    For example when changing the switching frequency from 100 kHz to 800 kHz in a digital controller that uses a 50 MHz PWM oscillator and a 9 bit DPWM register, the DPWM resolution changes from 9 bits to 6 bits.
  • LM5020EVAL Datasheet
    The PWM controller is designed for high speed capability including an oscillator frequency range to 1 MHz and total propagation delays less than 100 ns.

  • A comparative design view for accurate control of servos using a field programmable gate array
    In the actual implementation, the clk frequency supplied into the PWM circuitry on an FPGA could be either directly output from the oscillator or through Phase Locked Loops (PLLs). Altera FPGAs have different clk frequencies, for example, the APEX series has a 33 MHz clock while the Cyclone II series has a 100 MHz clk, which must be taken into account in the design.
  • Low temperature operation of a boost converter [for space power]
    The 87C752's PWM output has a fixed resolution of %bits (256 discrete values from 0 to 100 %). For an oscillator frequency of 16 MHZ , the maximum PWM frequency is 31.373 MHZ.
