LTpowerCAD 1

LTC3411 Project - 1.25A, 4MHz, Monolithic Buck Regulator (2.6-5.5V to 1.8V @ 1.3A)

LTspice® is a powerful, fast and free simulation software, schematic capture and waveform viewer with enhancements and models for improving the simulation of analog circuits.

LTpowerCAD^® is a power supply design program which selects power stage components, provides detailed power efficiency, shows quick loop Bode plot stability and load transient analysis, and can export to LTspice for simulation.

Product Details

Demonstration circuit 441 is a constant-frequency stepdown converter, using the LTC3411 monolithic synchronous buck regulator. The DC441 has an input voltage range of 2.65V to 5.5V, and is capable of delivering up to 1.25A of output current. See the LTC3411A for input voltages down to 2.5V. The output voltage of the DC441 can be set to 1.8V, 2.5V or 3.3V using the appropriate jumper connection, or it can be set to an adjustable value down to 0.8V, the reference voltage of the LTC3411.
