FAN4860UMP5X

FAN4860UMP5X is a low-power boost regulator. It is designed to provide a regulated 3.3V, 5.0V or 5.4V output from a single-cell lithium or Li-ion battery. Input current in shutdown mode is less than 1μA, which maximizes battery life. Light-load PFM operation is automatic and “glitch-free”. The regulator maintains output regulation at no load with as low as 37μA quiescent current. The combination of built-in power transistors, synchronous rectification, and low supply current make the device ideal for battery-powered applications. It is also used in applications such as USB “on the go” 5V supply, 5V supply – HDMI, H-bridge motor drivers, powering 3.3V core rails, PDAs, portable media players, cell phones, smartphones, and portable instruments.
