BD8312HFN

Datasheet 3.5V to 14V, 0.8A 1ch Synchronous Buck Converter Integrated MOSFET BD8312HFN General Description BD8312HFN can produce 1.2V, 1.8V, 3.3V, or 5V stepped-down output voltages from a power supply composed of 4 batteries, which can be Li2cell, Li3cell, or from a 5V/12V fixed power supply line. The built-in synchronous rectification switches are capable of withstanding up to15V. This IC has a flexible phase compensation system and a switching frequency of 1.5MHz allowing the use of smaller external output inductor and capacitor making the construction of a compact power supply really easy. Features  Built-In 1.0A/15V Pch/Nch Synchronous Rectification SW  On-Chip Phase Compensation Device between Input and Output of Error AMP.  Built-In Soft-Start Function.  Built-In Timer Latch System for Short Circuit Protection Function. Application For Portable Equipments like DSC/DVC Powered by 4 Dry Batteries or Li2cell and Li3cell, or General Consumer-Equipment with 5V/12 V Line...
