  • Single Supply Zero-Crossing Detector

    Created by LTspiceDesigner, published on 22-10-2014

    SPICE simulation of an ultra fast comparator LT1116 with falling-edge and rising-edge of 12ns.The comparator can operate either a single +5V or dual ±5V supplies.

    Project Type: Free

    Complexity Spice Software Software Version Full version Components number
    Simple LTspice IV No <10
  • Power Supply Battery Charger Controller

    Created by ICAP4Designer, published on 21-10-2014

    In this SPICE simulation, the MC33341 is configured as a source load low-side current sensing regulator, where the current is sensed in the ground return path of the power connection to the load. The regulator is designed for a 10V output voltage at 1 Ampere.

  • Dual Ideal Diode with Hot Swap Function

    Created by LTspiceDesigner, published on 18-10-2014

    The LTC4225 works as two ideal diodes. It's useful to replace two high power Schottky diodes and the associated heat sinks, in addition, the hot swap control MOSFETs allow boards to be safely inserted and removed from a live backplane by limiting inrush current in Micro Telecommunications Computing Architechture applications.

  • Full Bridge Inverter

    Created by StevenSandler, published on 15-10-2014

    SPICE simulation of a full bridge inverter configuration. Output switches are used in place of MOSFETs or IGBT, in order to simplify and speed up the simulation.

  • Half Bridge Simulation with State Machine Model

    Created by StevenSandler, published on 13-10-2014

    This simulation is performed with a state machine model, used to replace complex sets of circuitry. The block is described by an ASCII txt state file, where the first column defines the state, the second column defines the output for the state, the third column defines the expected input and the fourth column defines the state to transition to if the input is present during the positive edge of the clock signal. The state file of this circuit defines 128 states.
