Additional Infomation About Product

Datasheet 3. 5V to 14V, 0.8A 1ch Synchronous Buck Converter Integrated MOSFET BD8312HFN General Description Key Specifications Input Voltage Range: +3.5V to +14V BD8312HFN can produce 1.2V, 1.8V, 3.3V, or 5V Output Voltage Range: +1.2V to +12V stepped-down output voltages from a power supply Output Current: 0.8A(Max) composed of 4 batteries, which can be Li2cell, Li3cell, Switching Frequency: 1.5MHz(Typ) or from a 5V/12V fixed power supply line. The built-in Pch FET ON-Resistance: 450m(Typ) synchronous rectification switches are capable of Nch FET ON-Resistance: 300m(Typ) withstanding up to15V. This IC has a flexible phase Standby Current: 0A(Typ) compensation system and a switching frequency of Operating Temperature Range: -25C to +85C 1.5MHz allowing the use of smaller external output inductor and capacitor making the construction of a Package W (Typ) x D (Typ) x H (Max) 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. HSON8 2.90mm x 3.00mm x 0.60mm Application For Portable Equipments like DSC/DVC Powered by 4 Dry Batteries or Li2cell and Li3cell, or General Consumer-Equipment with 5V/12 V Lines Typical Application Circuit Input: 4.5V to 10V, output: 3.3V / 500mA V =4.5V to 10V BAT LX Figure 1.
