BD8313HFN

Datasheet 3.5V to 14V, 1.0A 1ch Synchronous Buck Converter Integrated MOSFET BD8313HFN General Description The BD8313HFN can produce stepped-down voltage from a power supply composed of 4 batteries, which can be Li2cell, Li3cell, etc., or from a 5V/12V fixed power supply line. Output voltages include 1.2V, 1.8V, 3.3V, or 5.0V. This IC allows easy production of a compact power supply since its high operating frequency of 1.0MHz requires small-sized external inductor and capacitor and the phase compensation components are integrated in the chip. The built-in synchronous rectification switches are capable of withstanding 15V. Features  Built-In Pch/Nch Synchronous Rectification SW Capable of Withstanding 1.2 A/15V.  Built-In Phase Compensation Device between Input and Output of Error AMP.  Built-In Soft-Start Function.  Built-In Short-Circuit Protection with Timer Application For Portable Equipments like DSC/DVC Powered by 4 Dry Batteries or Li2cell and Li3cell, or General C...
