Online Design and Simulation of the Semtech TS30012 DC/DC Switching Regulator Circuit

In this video we demonstrate the online design and simulation of the Semtech TS30012 DC/DC synchronous switching regulator evaluation circuit using TINACloud.

Startup Transient Simulation

The startup transient of a DC-DC converter is the period of time during which the converter is transitioning from its off state to its steady-state operating condition.

Redesigning the circuit

Let’s redesign the circuit to generate a 3.3 V output voltage.
The Design Tool changed the RTOP resistance to 26.7k and displayed a quick diagram of all the relevant analysis results, based on analytic calculations.

Steady State Analysis

Steady state analysis of a DC-DC power supply is the analysis of the circuit’s behavior when it has reached a steady state. This means that the output voltage is constant, except for the ripple voltage, and all the components in the circuit are operating in their steady state conditions.

Ripple voltages and current of the outputs

Line Step Analysis

Line stepping analysis of DC-DC converters is used to determine how a DC-DC converter responds to changes in the input voltage.

Load Step Analysis

Load step analysis of DC-DC converters is a type of circuit simulation that is used to determine how a DC-DC converter responds to changes in the load current.

Comparison of simulation and measurement results

The simulation results show good agreement with the voltage measurements in the TS300012 datasheet.

AC Analysis

AC analysis is a powerful tool for designing and optimizing DC-DC converters. It provides the frequency response of the converter, which can be used to analyze its stability and performance under different conditions.
