The LT3461/LT3461A are general purpose fixed frequency current mode step-up DC/DC converters. Both devices feature an integrated Schottky and a low VCESAT switch allowing a small converter footprint and lower parts cost. The LT3461 switches at 1. 3MHz while the LT3461A switches at 3MHz. These high switching frequencies enable the use of tiny, low cost and low height capacitors and inductors. The constant switching frequency results in predictable output noise that is easy to filter, and the indu.......

Battery-powered systems often stack cells in series to achieve higher voltages, but this is not always possible due to a lack of space. Switching converters use an inductor?s magnetic field to alternately store energy and release it to the load at a different voltage. With low losses they are a good choice for high efficiency. Boost, or step-up converters?covered here?provide higher voltage. Battery-powered systems often stack cells in series to achieve higher voltages, but this is not always po.......

The LTC3418 is a high efficiency, monolithic synchronous step-down DC/DC converter utilizing a constant frequency, current mode architecture. It operates from an input voltage range of 2. 25V to 5.5V and provides a regulated output voltage from 0. 8V to 5V while delivering up to 8A of output current. The internal synchronous power switch increases efficiency and eliminates the need for an external Schottky diode. Switching frequency is set by an external resistor or can be synchronized to an ext.......

Esta fuente se trata de otra pequeña SMPS (Fuente Switching) del tipo DC/DC (ingresa DC y egresa DC) en nuestro caso sea del tipo Step-Down o Buck Converter, que quiere decir que sera una fuente reductora. Basa su funcionamiento en base al integrado LM2596-adj el cual se encarga de todo el proceso de Switcheo de la bobina o choque, que gracias a ella se logra generar la acción de reducir la tensión, aunque en algunos casos también se puede utilizar como elevador (Boost o Step-Up).

This supply uses no heavy step down transformer and has an extremely low parts count. The circuit can be built very small and can supply small currents for small projects. The major downfall of this supply is that it is not isolated from the AC line and can only supply small currents.
