MCA design tool

Smallest body, just 3. These are used with the gates Xminus and Xplus to ensure that the reset pulse is shortened at its leading edge, and the set pulse is shortened at its leading edge. The latter can be obtained using the method described in the gEDA setup page. Some of the difference may be in the filter capacitor ESR and inductor series resistance which we have assumed as zero. In the lower centre of the circuit is the comparator that compares the feedback input with the reference voltage to gate the set pulses to the flip flop.

The charge current is modified by a voltage at the Ipk-sense pin to shorten the charge time and so reduce the maximum duty cycle.

No abstract text available Text: Note that the uic parameter in the transient analysis command, which says “use initial conditions”, is eseential to allow convergence to occur. With a large filter capacitor, this signal typically spans a number of oscillator cycles. Here is a set eex notes on the MC smps controller chip. This is about all that can be done with these graphs. Mountable with M3 screws! It is also valuable for gaining e intuition into how circuits work.

The low-pass filter at this point was necessary to ensure convergence.

The circuit in the top left of the diagram above is the oscillator. A well documented subcircuit file is given here. EX series products are listed by Underwriters’ Laboratories and CSA for use inproduct, the sx will have no heating problems.

In the top right of the circuit is the flip flop that drives the switching transistor. This chip has been around for quite a while and is very inexpensive.

Switching Mode Power Supply Design. The changes in oscillator slope and in the cycle period are clearly visible as the feedback gating signal turns on and off.

Buck Converter This is a straightforward dc-dc converter that rx an output voltage less than the input voltage. The theory of operation is well ec in reference 2 of the resources. The transistors need to have some capacitances and resistances to be specified to avoid convergence problems. The model is different to the AEi model but makes use of some information about MC behaviour.

For designing dc-dc converters, the datasheets have a table of formulas that may be used, however this should not be a replacement for understanding of the circuit operation as the designs may need to be tweaked for a variety of reasons.

The reason for this is that at least one capacitor inside the MC model has initial conditions. To improve performance this was replaced with a controlled hysteresis switch similar to that used in the AEi model. To get a basic simulation going try the following commands. This is a straightforward dc-dc converter that produces an output voltage less than the input voltage.
