  • UltraVolt HVPS Output-Current Monitor
    as a correction current. The analog-summing circuit is easily implemented, since the polarity of the output-voltage test point is opposite that of the output-current monitor. It is important to note, the internal-divider leakage current is directly proportional to output voltage and reduces linearly
  • SP720, SP721 and SP723 Turn-On and Turn-Off Characteristics (.pdf)
    input (shown here as. active, dissipation at the junction is the Zener voltage times the. R1). This will add resistance to limit current into the CMOS. current. When the SCR structure becomes active, it latches on. IC by forming a current divider with the latched-on SCR. with low resistance and low
  • Fractional-N Synthesizers (.pdf)
    latch to add the contents of its input to its current. an analog representation of the PLL accumulated phase error and. output on each cycle of the clock. It behaves as the digital equiv-. is used to phase modulate the PLL to cancel the analog error. alent of an integrator and since the integral
  • Basics of Dual Fractional-N Synthesizers/PLLs
    integer-N synthesis. [1,5]. Among these methods, three techniques are best known in the. industry: fractional divider-based, current injection-based, and. ?S modulator-based fractional-N. This White Paper describes. these methods and provides a general discussion of the use of. fractional-N synthesizers
  • Simple Synchronous Buck Converter Design - MCP1612
    are internal and switching is 1.4 MHz, the inductor, input and output capacitor size is minimized. The output voltage is set by using a simple resistor divider, with a high-bandwidth loop being accomplished by a series resistor capacitor to ground. Efficiencies of 90% and a typical shutdown current

  • ENERGY STAR (R) Compliant - Low Cost LED Dimming
    This circuit can be thought of as having two separate portions. There is a LED management portion and there is a dimmer management and PWM Signal portion. The LED management portion charges the output capacitor to a "DC" state. The dimmer management portion provides loading current for an SCR
