Consumer demand is driving the mobile phone reference design and chipset design company in their equipment to provide more multimedia features, but this core processor heavy burden, and thus promote dynamic voltage scaling (DVS) and other energy-saving technology the demand. Fairchild (Fairchild Semiconductor) to provide a 6MHz, 800mA/1A digital programmable buck Power choke product FAN5365, with excellent dynamic performance, high efficiency and small footprint, a systems engineer design the ideal complement PMIC the product.

FAN5365 uses 1.27mmX1.29mm of 9-bumpWLCSP package, is the smallest 6MHzDVS buck, compared to the previous solution volume is reduced up to 40%, as smart phones, ultra mobile PC, tablet PCs and wireless broadband hotspot device such as a single lithium-ion battery-powered equipment ideal core processor-powered devices.

FAN5365 has excellent transient response performance, high efficiency at light load PFM mode consumes only 40μA of quiescent current. For larger loads, this Automatic Voltage Regulator will automatically convert the fixed frequency of 6MHz PWM mode, allowing designers to use low-cost small chip inductors and capacitors. FAN5365 supports up to 800mA or 1A of load current, it also provides a pin-selectable output voltage of two or I2CBus? Interface, programmable output voltage to 0.75V to 1.975V in 12.5mV increments within the regulation.

In addition, FAN5365 support from a wider range of 2.3V to 5.5V Li-Ion battery voltage range, and provides advanced protection features including current limiting short circuit protection, thermal protection and undervoltage lockout.

Fairchild FAN5365 is a comprehensive range of DVS buck converter product family, allows engineers to integrate functionality, improve performance and reduce the equipment size and overall number of components, thus promoting design innovation.
