ST provides a wide portfolio of high-performance step-up (boost) switching regulators, with both synchronous and non-synchronous switches and charge pump ICs. Other features include micropower operation with very low supply current, high efficiency, small size, adjustable or synchronizable switching frequencies, and current generators for LED driving.
ST8R00 boost regulator:
The ST8R00 is a step-up DC-DC converter featuring an output current cut-off function. This boost converter is ideal for use where designers have tight constraints in terms of PCB area and cost.
In demanding applications such as Blu-ray disc players/recorders, laptops and game consoles, the ST8R00 allows significant reductions to be achieved in both the PCB area and the manufacturing cost, without sacrificing performance
