The LTC4013 is a high voltage battery charger controller that supports float, absorption and equalization lead-acid and constant-current/constant-voltage Li-Ion charging algorithms. It is particularly well suited for charging a wide range of lead-acid batteries, including both vented and sealed type. The LTC4013 also supports Li-Ion/Polymer, LiFePO4, NiMH, NiCd and other battery types. Charging is performed with a high efficiency synchronous buck (step-down) converter that uses external N-channe.......

"The buck-boost regulator circuit delivers -5V output. I hoped this would a nice way to generate a negative voltage for e. g. an LCD-display. However this circuit requires component values that are similar to the buck regulator at high load." Experiments with the LM2575 Here is a nice way of using this regulator, this can be used for CMOS opamps as you have a -5V too. That means a portable........

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). La teoría.......
