austriamicrosystems has introduced a 200 mA boost converter that provides a continuous transition between boost and regulated buck mode which makes the device ideal for single for dual cell ...

Figure 1: In a step-up converter, all you have to do to change the output voltage is change the duty cycle of the switching signal. Interestingly, the circuit raises the voltage by changing the duty ...

Linear Technology’s LTC3119 is an efficient, monolithic buck-boost converter that operates with inputs from 2.5 to 18 V (Fig. 1), making it well-suited to operate from one- to four-cell Li-ion ...

Non-isolated IBCs are being designed into many new applications, which significantly reduce the solution size and cost while also increasing the operating efficiency and providing design flexibility.
